Commit 12967c3e13 incorrectly made the target optional.
The validation was re-introduced by commit e8863b91f (which
put it into FSDefValidate instead of the parser), but
it did not amend the schema to make it mandatory again.

The nature of Fedora rawhide means that it will inevitably have failures
periodically. Currently it is failing to even update packages due to
glibc switching to use of clone3 syscall, which is mistakenly blocked by
seccomp in container runtimes using EPERM instead of ENOSYS.
When we fail to build the rawhide containers, it is quite likely that we
still have the previous build available in the gitlab registry, so it is
reasonable to allow the container job to fail and try the build job
anyway.
Ideally we would ignore the container build failure if-and-only-if the
previous container was build with the same list of packages. We don't
record the original dependency package list though, so that's not
currently possible.

In our case we are just changing between read-only and read-write modes

In one of my previous patches I've tried to postpone dropping
CAP_SETPCAP until the very end because it's needed for
capng_apply(). What I did not realize back then was that we might
not have the capability to begin with. Because of unknown reasons
capng_apply() pollutes logs only for CAPNG_SELECT_BOUNDS and not
for CAPNG_SELECT_CAPS.
Reproducer is really simple: run libvirtd as a regular user.
During its initialization, libvirtd will spawn some binaries
(dnsmasq, qemu-*, etc.) and while doing so it will try to drop
capabilities.
Anyway, let's call capng_apply(CAPNG_SELECT_BOUNDS) only if we
have the CAP_SETPCAP (which is tracked in need_setpcap variable).

After all capabilities were set (except for CAP_SETGID,
CAP_SETUID and CAP_SETPCAP) and after UID:GID was changed we drop
the last aforementioned capabilities (we couldn't drop them
before because we needed UID:GID and capabilities change).
Therefore, there's final capng_apply() call. However, it is
wrapped in one layer of parenthesis more than needed.

Libvirt is using the G_GNUC_FALLTHROUGH macro provided by glib since
version 2.60. Since we need to support older glib, we also have some
compatibility code to define it if missing.
We set the GLIB_VERSION_MAX_ALLOWED macro to ensure we get warnings
when we use an API that dates from a glib version newer than our
minimum benchmark. Historically this didn't get enforced for (most)
macros, but GLib 2.69 has addressed that gap.
This causes our usage of G_GNUC_FALLTHROUGH to trigger warnings.
GLib is right to warn, because it does not know that we have added
our own fallback for older versions.
The only way to squelch this warning though, is to fully undefine
the GLib provided G_GNUC_FALLTHROUGH and use our own in its place.
We'll be able to remove all this compat burden when we finally
update the min glib version to be >= 2.60

If lvcreate found an existing signature when trying to create a

action failed due to inability to answer interactive question to
wiping it (lvcreate assumed 'no' was the answer). With added
option --yes to the command line, the answer to any interactive
question is assumed to be yes. Therefore, lvcreate wipes the
signature and the new volume is created successfully.
