[Pkg-libvirt-maintainers] Bug#833745: libvirt-daemon-system: Please use SIGUSR1 to restart virtlockd and virtlogd on upgrade

[Laurent Bigonville]

Package: libvirt-daemon-system
Version: 2.1.0-1
Severity: normal

Hi,

According to the virtlockd and virtlogd manpages, SIGUSR1 can be used to
reexec the daemon to minimize the downtime on upgrade:

This should probably be prefered over a full restart. Not that virtlogd
doesn't seem to be restarted on upgrade ATM.

Cheers,

Laurent Bigonville
