When build ubuntu iso image, it will install grub-efi-amd64-signed
and grub-efi-amd64 packages. Both of the postinst script will try
to find root device and install grub which will definitely fail in
such a chroot environment.
So the workaround is to skip error and remove postinst script.
And confirm the package be installed successfully at last.

As described in the comments, CentOS overrides the "distroverpkg"
variable in yum.conf. This is the package that yum queries to
establish the value of the $releasever variable. On other platforms,
this defaults to "redhat-release" (which "fedora-release" provides) so
everything works. It is only when the base-system "distroverpkg"
refers to a package not in the chroot we hit the issue.
We can avoid this by setting the releasever variable via the
commandline.

I recently built a ramdisk for IPA and was confused by
the fact that the source-repositories name did not
match the element name. (this is a convention,
confusing when they don't match but certainly not
required).
This patch makes it so you can use DIB_REPOREF_ironic_agent to
customize the IPA ramdisk sources when building ramdisks.
For backwards compat if DIB_REPOREF_agent is set it automatically
sets the new DIB_REPOREF_ironic_agent to that value as well.

Troubleshooting an image can be quite hard, specially if you can not get
a prompt you can enter commands to find out what went wrong. By default,
the images (specially ramdisks) doesn't have any SSH key or password for
any user. Of course one could use the ``devuser`` element to generate
an image with SSH keys and user/password in the image but that would be
a massive security hole and very it's discouraged to run in production
with a ramdisk like that.
This commit is adding a new element called dynamic-login, which inserts
a helper script into the image to allow operators to inject a SSH key
and/or change the root password dynamically when it boots via parameters
in the kernel command line.
Those parameters are:
sshkey = If the operator append sshkey="$PUBLIC_SSH_KEY" to the kernel
command line on boot, the helper script will append this key to the root
user authorized_keys.
rootpwd = If the operator append rootpwd="$ENCRYPTED_PASSWORD" to the
kernel command line on boot, the helper script will set the root password
to the one specified by this option. Note that this password should be
an encrypted password.

When the kernel gets installed on Fedora, the rpm post scripts call
"/bin/kernel-install" [1] to install it. This is a script provided by
systemd.
However, in [2], Fedora ships a patch to kernel-install that makes a
call-out to /sbin/new-kernel-pkg -- the install script provided by
grubby [3]
Without grubby installed, systemd's kernel-install script goes off and
runs dracut plugins directly [4], which eventually creates the initrd.
For reasons that are not clearly explained, the initrd will end up in
a a "machine-id" sub-directory of /boot (possibly, so you can symlink
it?). It is also called "initrd", even though it's an initramfs, for
historical reasons in dracut I think.
It is at this point that I think 99-ramdisk has been written to move
the generated initrd file back into /boot. Later on, when we build
the image, we run grub-install and it picks up the kernel and the
initrd and installs everything.
grubby's new-kernel-pkg [6] it's very similar -- it uses dracut to
make the initramfs ... but in this case it is put in /boot and is
actually called initramfs.
The subtle change that led me down this path is that dracut has been
modified to have a "Recommends" for grubby for >F22 [7]. After
discussing this change with the author, it turns out it was *always*
intended to use the grubby-based kernel install scripts for Fedora --
our builds have been incorrect in not including the package. The
author got sick of people removing the package and making unbootable
systems, hence the change.
Thus this removes the workarounds in 99-ramdisk and replace it with an
install of the grubby package. grubby's kernel install script will
put the kernel & generated initramfs in /boot, and it will be
installed correctly via the usual grub install later when we build the
disk image.
I have built F22 & F23 fedora-minimal images with this and they boot.

On Debian/Ubuntu installs of RPM, /usr/lib/rpm/macros sets
%_dbpath %(echo $HOME/.rpmdb)
which makes quite a bit of sense, because RPM is not the system
packager and thus RPM is setup to install things into a hierarchy in
the users homedir.
However, this messes things up when building a Fedora chroot on an
Ubuntu platform.
We use RPM & yum from the base-system to bootstrap the Fedora chroot.
While both obey --root flags, they still pick up the %_dbpath macro
and so end up creating the RPM database in <chroot>/home/user/.rpmdb
After we have bootstrapped yum/dnf, we execute further installation
commands from inside the chroot -- where we now have the Fedora
version of /usr/lib/rpm/macros and hence have _dbpath set to
/var/lib/rpm -- except there is no rpm database there.
Should anyone be finding this in the future, the actual issue that
appears is
$ sudo chroot /opt/dib_tmp/image.b6B5S3f6/mnt dnf makecache
Error: Failed to synchronize cache for repo 'fedora' from \
'https://mirrors.fedoraproject.org/metalink?repo=fedora-$releasever&arch=x86_64': \
Cannot prepare internal mirrorlist: file "repomd.xml" was not found in metalink
Note the issue there is that $releasever is not expanded, because the
rpmdb where this info is kept is not populated.
The trick is to make sure we override this value when using the host
rpm/yum to setup the chroot. The bare rpm calls, which we use to
install the repos, have a --dbpath argument where we can override
this. yum does not however, so we override this in the global
~/.rpmmacros while we are installing the packaging tools and
dependencies into the chroot.
Copious comments are included, because this is super-confusing.

fedora-minimal fails to build on Ubuntu Trusty due do being unable to
find the initrd (see Id4c04d7ae20068643df34d2fa31068e8a917a52d).
This is a rather obscure problem that comes from the intersection of
several things.
The first thing to note is that the post-install scripts of the
kernel-core package use kernel-install [1]. For whatever reason, this
installs the kernel to /boot/MACHINE-ID/KERNEL-VERSION
MACHINE-ID comes from /etc/machine-id; a UUID that should have been
created by the systemd post-inst scripts with systemd-machine-id-setup
[2].
The chroot environment provided for root.d elements has no kernel
file-systems like /proc or /dev mounted. This is where differences in
the base-system come into play -- on more recent systems that
implement getrandom() systemd does not need /dev/urandom to generate
the machine-id [3]; we get a value and /etc/machine-id is populated.
On older platforms (Trusty), systemd-machine-id-setup fails (unable to
access /dev/urandom) and we end up with a blank /etc/machine-id. This
ends up making kernel-install (the script) fail during yum's
installation of kernel-core, which means the initrd is not installed
correctly.
We end up bailing out in fedora-minimal/install.d/99-ramdisk, where we
try to put the installed ramdisk in /boot for the later grub install
scripts to find.
The solution here is to mount the standard kernel file-systems within
the chroot before we try installing.

5af25b5f fixed the hostname of Debian images to "debian" since a lack of
hostname definition set the hostname to "(None)".
It has been done by introducing /etc/cloud/cloud.cfg.d/01_hostname.cfg
with content:
hostname: debian
Review supposed the hostname would be overriden by cloud meta-data. That
might have stand true for Wheezy but it is not the case for Jessie.
cloud-init 0.7.6 ignores cloud metadata whenever "hostname" or "fqdn"
are set in a config file. Roughly:
# no fqdn set, get fqdn from cloud
# get hostname from cfg if available otherwise cloud
fqdn = cloud.get_hostname(fqdn=True)
if "hostname" in cfg:
# hashar: set from config file NOT cloud
hostname = cfg['hostname']
else:
# fallback to cloud
hostname = cloud.get_hostname()
Relevant code is

Without this patch, the devuser element attempts to find public keys by
iterating over the string "rsa dsa". When two keys are grouped together
in quotes, a bash for loop treats it as a single key. You can see the
issue this causes when debug output is turned on:
+ for fmt in '"rsa dsa"'
+ '[' -f '/home/krinkle/.ssh/id_rsa dsa.pub' ']'
This is not a reasonably named key to look for, so this patch removes
the quotes so that the loop will look for id_rsa.pub and id_dsa.pub
separately.

Make sure we reset the yum/dnf cache to /var/cache/${YUM}, not just
/var/cache/yum
This was resulting in the F22 fedora-minimal image being larger than
the base-image. Because F22 fedora-minimal does some installs with
dnf when bootstrapping the chroot before we set "cachedir=" to the
bind-mounted external cache, we have "/var/cache/dnf" created and and
populated with the package meta-data, etc.
When we globally point dnf to /var/cache/yum here, we effectively
orphan the /var/cache/dnf created in those first steps. dnf doesn't
care, but we end up with two copies of all the package metadata, etc
in "/var/cache/dnf" & "/var/cache/yum".
This also cleans up the sed a bit, by just replacing the lines.

The ironic-agent element is created using the disk-image-create utility

In Id1e430e7d050a0b99ac449e2ea435e06cda1c4e6 I made the mistake of not
actually removing grub in 15-remove-grub.
This restores the removal phase and adds a bunch of comments. It
seems the centos7 and centos (6) images have grub2 installed, but F22
does not; hence the check.
For anyone interested in the history; it seems the whole idea of
removing grub and re-installing it in the finalise stage is to do with
Ubuntu grub scripts failing in the chroot. It is not clear this does,
or has ever, affected rpm based systems; but that's how it is, so
leave well enough alone.
The whole reasoning behind the rpm download & re-install is actually
explained in If095adc4abb52a19a3aa0b1caebfb3e4d8f605ef, but over time
the comments got lost as code moved around. I've restored in here

Appears that growroot was running before /dev is mounted so the script
is unable to introspect the filesystem partition info. Run this after
all local filesystems are mounted to fix this issue.

We can resize the rootfs without the initrd based approach. Create a
growroot element which performs rootfs resizing as part of system init.

There is a bug where the init scripts element incorrectly munges the
install path making it useless. Also removing the dep on rsync since
this occurs from inside the chroot.

This patch is reducing the size of the ramdisk image generated by the
ironic-agent element. It does remove extra packages (graphical stuff,
dev stuff, miscs, docs, etc...) and purges directories that are not
needed for a ramdisk (like /boot since it boots using an external
kernel)
Currently it was tested generating a Fedora 22 image and reduced the
size of the final image from 464 MB to 211MB compacted (54% decrease).
I was able to boot a VM with 1.3 GiB of ram instead of the previous 3 GiB
needed.

The default value was set in the centos7 element, but not
exported, which caused issues in rpm-distro. Also changed
a test in rpm-distro to only check for DIB_RELEASE > 22
if it's fedora.

The script for ironic-agent utilizes curl, however an extremely
minimal system may not have it, and as such we should list it as
a package that must be installed to support the element.

As described in the comments, sfdisk was rewritten for util-linux 2.26
(as shipped in F22) and now interprets arguments a sectors, rather
than cylinders.
The current partitioning line is "1 - - *" (start/size/type/bootable)
which means you start getting:
---
/usr/sbin/grub2-install: warning: this msdos-style partition label has
no post-MBR gap; embedding won't be possible.
/usr/sbin/grub2-install: warning: Embedding is not possible. GRUB can
only be installed in this setup by using blocklists. However,
blocklists are UNRELIABLE and their use is discoura ged..
/usr/sbin/grub2-install: error: will not proceed with blocklists.
---
when building images, because the start is interpreted by the new
sfdisk as sector 1 and it crams the partition right next to the MBR.
Specifying "-" for the size is undefined in the man page; even reading
the source it's not totally clear what "-" for the size does [2]. In
any case, the alignment is wrong in sectors or cylinders; we want to
be a multiple of 4KiB for best performance.
The intent here is to create one single, Linux, bootable, partition
taking up the whole disk starting at 1MiB, so "2048 + L *" makes this
clear.
We use the -uS argument to ensure both versions treat this start-value
as a sector offset (newer sfdisk essentially ignores the argument).
As described in the comments, bugs in the older sfdisk necessitate
usage of "--force".
Although we could choose more or less, it seems most common to align
to a 1MiB boundary (i.e. starting at sector 2048). libguestfs has
some disucssion around --alignment and where it sets it's default to
this [3]. The 2.26-era sfdisk also defaults to putting partitions
here. 1MiB should be enough for GPT schemes in the future as well.

Using the default release for the Debian test-element leaves
us at the mercy of packaging problems in Debian unstable. Since
we only care if the image itself builds, use the safe choice of
Debian stable.

Splits the install.d into source-install and package-install in
order to allow building from a distro packaged version of
ironic-python-agent.
Change-Id: I17513c29efd8c199e07ac1ef20ea5d7456585413
Adds support for Ubuntu and Debian to ironic-python-agent. This will
enable building ramdisk with Ubuntu and Debian as base OS.
Updated README to further clarify what the element does.

interfaces are not configured at all because specific interface files
are created but not sourced. This will result in the VMs running with
the loopback interface only
This is a regression, the problem was already fixed in the past, see commit
b822581d88

The resize module is problematic for using grub on very large root
partitions. It is also extremely slow on large partitions, and users are
likely better off creating new partitions in the empty space.
