This reverts commit 8355d42dd3.
After some discussion upstream [1] this patch turns out to be spurious.
It better gets reverted prior to a release.

|
virtlockd - libvirt lock management daemon
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
B<virtlockd> [ -dv ] [ -f config_file ] [ -p pid_file ]
|
|
|
|
B<virtlockd> --version
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
The B<virtlockd> program is a server side daemon component of the libvirt
|
|
virtualization management system that is used to manage locks held against
|
|
virtual machine resources, such as their disks.
|
|
|
|
This daemon is not used directly by libvirt client applications, rather it
|
|
is called on their behalf by B<libvirtd>. By maintaining the locks in a
|
|
standalone daemon, the main libvirtd daemon can be restarted without risk
|
|
of losing locks. The B<virtlockd> daemon has the ability to re-exec()
|
|
itself upon receiving SIGUSR1, to allow live upgrades without downtime.
|
|
|
|
The virtlockd daemon listens for requests on a local Unix domain socket.

|
|
|
|
=item B<-d, --daemon>
|
|
|
|
Run as a daemon and write PID file.
|
|
|
|
=item B<-f, --config> I<FILE>

|
Use this configuration file, overriding the default value.
|
|
|
|
=item B<-p, --pid-file> I<FILE>

|
|
=head1 SIGNALS
|
|
|
|
On receipt of B<SIGUSR1> virtlockd will re-exec() its binary, while
|
|
maintaining all current locks and clients. This allows for live
|
|
upgrades of the virtlockd service.
