+ ==== Update ====
+ Here is a simple reproducible testcase. This break with both ext4 and xfs,
+ but only on quantal. On raring it works correctly.
+
+ touch xxx
+ setfacl -m user:ubuntu:rw- xxx
+ setfacl -m group::--- xxx
+ getfacl xxx
+ chmod g+rw xxx
+ getfacl xxx
+
+ You'll see:
+ # file: xxx
+ # owner: serge
+ # group: serge
+ user::rw-
+ user:serge:rw-
+ group::---
+ mask::rw-
+ other::r--
+
+ In raring (and precise), the group acl gets update to be rw-.
+ ================
+
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.
** Summary changed:
- udevadm trigger --action=change not working since quantal?
+ chown does not update acls if there are >1 user acls (in quantal)
