Basically, the only way to solve this problem 100% in userspace would
be with a userspace daemon running as a privileged user, and some kind
of Unix domain socket.
Patches to implement this in the e2fsprogs UUID library would be
greatfully accepted.
This patch creates a userspace uuidd which correctly generates
time-based (version 1) UUID's, with the clock sequence number stored
in the filesystem so we correctly detect time going backwards across
processes and even across reboots.
I believe this patch is a better solution than Helge's kernel patch
solution or the kludgy patch to e2fsprogs in the the SLES RPM which
tries to solve this problem in another way, but which has been
problematic in the past.
Helge, could you try this out and see if it meets your needs?

commit 84e7405d89cb79b43d84e86051bf2f34d9ae5216
Author: Theodore Ts'o [EMAIL PROTECTED]
Date: Mon Dec 10 00:22:16 2007 -0500
Add uuidd daemon to prevent duplicate time-based UUID's
Also store the clock sequence information in a state file in
/var/lib/misc/uuid-clock so that if the time goes backwards the clock
sequence counter can get bumped. This allows us to completely
correctly generate time-based (version 1) UUID's according to the
algorithm specified RFC 4122.
