Bug#810141: libvirt-daemon-system postinst tries to touch files in nonexistent dirs

[Nick Phillips]

Package: libvirt-daemon-system
Version: 1.2.9-9+deb8u1
Severity: normal

On upgrade from wheezy to jessie, libvirt-daemon-system failed to complete
installation - postinst was trying to touch /var/log/libvirt/uml/.placeholder
and /var/log/libvirt/lxc/.placeholder - when neither of those directories
exist.

Had to manually create dirs in order for postinst to complete.

The dirs are created by the package itself, e.g.

dpkg -S /var/log/libvirt/uml

So if that failed, dpkg did not create the dirs (e.g. due to some
--path-exclude pattern).

We'd need more logs to tell. We had lots of successful upgrades from
wheezy to jessie already, can you think of s.th. that could be different
on your system?
Cheers,

Yes, that's possible. You shouldn't have to remove the package and I
think that what made the dpkg fail to take over the dirs from another
libvirt-bin to libvirt-daemon-system.

So I think there's no bug in libvirt itself here related to the
directories. The problem with the registration of the service would be a
bug though but I would need to know how to reproduce.
