  Hum, how did you get this ? Maybe this is more a packaging problem than
anything else

Yes, it was, sorry...

, I have this here:

[root@paphio ~]# rpm -qf /var/run/libvirt
libvirt-0.4.1-3.fc8
[root@paphio ~]# rpm -V libvirt
[root@paphio ~]# ls -ld /var/run/libvirt
drwxr-xr-x 2 root root 4096 2008-04-04 18:00 /var/run/libvirt
[root@paphio ~]# ls -l /var/run/libvirt
total 0
srwxrwxrwx 1 root root 0 2008-03-29 14:56 libvirt-sock
srwxrwxrwx 1 root root 0 2008-03-29 14:56 libvirt-sock-ro
[root@paphio ~]#

  I don't know, that's doable too, but if there is a packaging problem
maybe it's good to have it fixed instead of changing permissions at
runtime. But the configuration data should override this, that's true.
What do others think ?
