6a1eb2457c Move selinux restore to end of finalise
After a bit of spelunking, I90d0c96d5659326ba67d6119b96d9a4113adf7fe
was the original change that introduced the setfiles here rather than
autorelabel at boot time.

Touching the autorelabel file probably makes sense somewhere low, but
when we start relabling the file system we really should be doing that
as late as possible so we fix up everything that has come before.
Move this to 90 to capture this.

fe559242cb Dont fail if were missing setfiles
We are using which to find the location of setfiles. Our script is set
-e though, and we need to also be able to handle the case where setfiles
does not exist (like on centos-minimal).

7514fc066f Use environment setfiles
Hard coded path fails on Distros (such as el6) with setfiles bin
in different places, for example, rhel6 has this in /sbin/setfiles

36b59c001c Standarise tracing for scripts
There is a wide variety of tracing options through the various shell
scripts.  Some use "set -eux", others explicity set xtrace and others
do nothing.  There is a "-x" option to bin/disk-image-create but it
doesn't flow down to the many scripts it calls.

This adds a global integer variable set by disk-image-create
DIB_DEBUG_TRACE.  All scripts have a stanza added to detect this and
turn on tracing.  Any other tracing methods are rolled into this.  So
the standard header is

---
if [ "${DIB_DEBUG_TRACE:-0}" -gt 0 ]; then
    set -x
fi
set -eu
set -o pipefail
---

Multiple -x options can be specified to dib-create-image, which
increases the value of DIB_DEBUG_TRACE.  If script authors feel their
script should only trace at higher levels, they should modify the
"-gt" value.  If they feel it should trace by default, they can modify
the default value also.

Changes to pachset 16 : scripts which currently trace themselves by
default have retained this behaviour with DIB_DEBUG_TRACE defaulting
to "1".  This was done by running [1] on patch set 15.  See the thread
beginning at [2]

dib-lint is also updated to look for the variable being matched.

9009b18869 setfiles consistently
Working on host systems without selinux, where the guest image
does have selinux, creates a situation where the instance will
have about a 1 minute delay on first boot because it must relabel.
The previous check for sysfs assumes that the host system has
selinux, which is not needed for the guest setfiles to work.

e92398a318 Relabel filesystem if SELinux is available
Relabel the filesystem during image builds if SELinux is supported
in the kernel of the build machine and userspace tools are available.

Otherwise touch /.autorelabel to schedule a relabel the first time
the image boots. We relabel when possible because it decreases first
boot time.

4e68a7965b Remove fixfiles from rpm-distro finalize
Running fixfiles after setfiles is redundant. setfiles
already corrected the SELinux file security contexts.

f6ba2aeaf4 set -e all the things
Using set -e in all of our scripts will prevent some subtle bugs
from slipping in, and will allow us to enforce use of set -e with
tooling.

This change also adds -u and set -o pipefail in the less complex
scripts where it is unlikely to cause problems.  A follow-up change
will enable those options in the complex scripts so that if it
breaks something it can be reverted easily.

ea257c96d9 Skip relabel unless SELinux is enforcing
The SELinux relabel of the filesystem is taking almost 2 minutes and
isn't needed unless you actually plan to run with SELinux enforcing.
Plus, it appears to "leak" out of the chroot, referencing filesystems on
partitions that aren't even mounted in the chroot.

Note you just can't use getenforce or selinuxenabled here to get the
state of SELinux because those commands are not accurate inside a
chroot.

TBH, a downside of this is that if someone goes to try to enable SELinux
in an image where it was built with it not enabled, the file contexts
are going to be wrong. So they'd need to relabel themselves at that
point. However, this saves me quite a bit of time during image builds,
so I thought I'd submit to get other folks opinion on it.

301c3c4475 Extracting common functionality for rpm based distros
Rather than dublicating code to implement rhel or any
other derivitive, this patch introduces an rpm-distro
element that should be used as a dependency.
