it was noted that only old versions of kerberos would need the

When using systemd we want to take advantage of socket activation
instead of keeping daemons running all the time, so we default to
shutting them down after two minutes of inactivity.
At the same time, we want it to be possible for the admin to opt
out of this behavior and disable timeouts entirely. A very natural
way to do so would be to specify a zero-length timeout, but that's
currently not accepted by the command line parser. Address that.

When redefining checkpoints from scratch we'd not set the 'current'
checkpoint if there wasn't any. This meant that the code wasn't ever
able to set a 'current' checkpoint as any other one looks up if the
parent of the redefined checkpoint is current.
Since the backup code then requires the current checkpoint to start the
lookup we'd not be able to perform a backup after restoring the
checkpoint hierarchy.

The original intentions were to skip the backing store update with

Fix it by only asserting the boolean which was used to track whether we
support update of the backing store only when blockdev is not present

qemu: start/stop an event loop thread for domains
A bogus comment was added claiming we didn't need to shutdown the
event thread in the qemuProcessStop method, because this would be
done in the monitor EOF callback. This was wrong because the EOF
callback only runs in the case of a QEMU crash or a guest initiated
clean shutdown & poweroff. In the case where the libvirt admin
calls virDomainDestroy, the EOF callback never fires because we
have already unregistered the event callbacks. We must thus always
attempt to stop the event thread in qemuProcessStop.
