[Bug 1092715] [NEW] udevadm trigger --action=change not working since quantal?

[Serge Hallyn]

Public bug reported:

For bug 1057024, we have qemu-kvm postinst call udevadm trigger
--action=change.  This is to make udev recalculate permissions for
/dev/kvm based on the new /lib/udev/rules.d/40-qemu-kvm.rules file.

In precise, this causes /dev/kvm's acls to be correctly set so that
group has rw permissions.

In quantal, with the exact same rules file, it does not.  After a
reboot, permissions are set correctly.  But manually running udevadm
trigger --subsystem=misc --action=change (or variations of that) does
not change the group acl.  It changes the group ownership, and part of
the acl, but not the group acl.
