There are some network file systems that do support XATTRs (e.g.
gluster via FUSE). And they appear to support SELinux too.
However, not really. Problem is, that it is impossible to change
SELinux label of a file stored there, and yet we claim success
(rightfully - hypervisor succeeds in opening the file). But this
creates a problem for us - from XATTR bookkeeping POV, we haven't
changed the label and thus if we remembered any label, we must
roll back and remove it.

Currently during RPM upgrade we restart libvirtd and unconditionally
enable use of systemd socket activation for the UNIX sockets.
If the user had previously given the --listen arg to libvirtd though,
this will no longer be honoured if socket activation is used.
We could start libvirtd-tcp.socket or libvirtd-tls.socket for this,
but mgmt tools like puppet/ansible might not be expecting this.
So for now we silently disable socket activation if we see --listen
was previously set on the host.

When using systemd socket activation the --listen arg has no

This helps the admin discover the change in behaviour and thus decide
whether to stick with socket activation or revert to previous behaviour.
