As described in the comment, systemd will create a broken
/etc/resolv.conf link if there is no file in the base-image (as you
can read in the bug, it is debated if this is a bug or a feature).
The solution is to leave a dummy /etc/resolv.conf file in the image.
Whatever network manager you choose (NetworkManager, glean,
cloud-config, etc) will overwrite this anyway.
It's just that some tools, such as dhclient, get confused with the
broken symlink. This affects you if you're using glean to configure
the network in a DHCP situation, for example -- dhclient won't
configure nameservers and everything goes to heck.

With a slow file system, umount can return 0 and the immediately
following remove can fail with a "Device or resource busy" error.
This happened in DevStack in disk-image-create where unmount_image
is followed by an immediate cleanup_build_dir.
Solution is to apply same logic from bug 1332521 to allow the
remove to retry on failure (up to 5s) in case the umount has not
completed.

We perform a check for this file after an image build fails to see if it
was intentional. This outputs a message which looks like the failure is
a result of the check when the file is missing which is very confusing
to users. Lets be more quiet about it.

In order to add more flexibility to the vm and bootloader
elements, split the functionality in two different ones, and
make vm depend on bootloader element.
This will allow to construct more elements that depend on

Vlan support was recently added to glean. However, if the 8021q module
is not loaded, glean will fail to bring up a tagged interfaced defined
in /etc/network/interfaces.d/. Manually attempting to bring up the
interface results in an error[1]. This patch ensures that the 8021q
module is loaded so that tagged interfaces can be brought up at boot.

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.

This patch is a follow up patch fixing some nits left by the review
25d3ee5471.
It does:
* Fix the README file to say that the password *must* be encrypted and
the option values *must* be quoted
* Adds Type=oneshot in the upstart service config file so that upstart
will not try to restart the service over and over.
* Enable setu, sete and setpipefail in the dynamic-login script

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.

This patch is extending the root device hints to also look at
ID_WWN_WITH_EXTENSION and ID_WWN_VENDOR_EXTENSION from udev.
Prior to this patch the bash ramdisk only cared about ID_WWN but in some
systems in some platforms with a RAID controller, this ID can be same
even if they are different disks (see bug 1516641).

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.
