kudzu should detect any active logical volumes and add the apropriate
entries to fstab.
kudzu doesn't touch /etc/fstab currently.
I suppose HAL could do it, but generally fstab-sync has been
more targeted at removable devices.
Well, I don't know if hal (or fstab-sync) is the aproprieate
component, but Fedora detects standard partitions whe booting, then it
should also detect active logical volumes, I think. If I install Suse
(with reiserfs or ext3) in a another partition, when I boot Fedora,
the newly discovered partitions is added to fstab, but if I install
FC3T2 (using LVM2) it is not added.
This would be nice to have but it requires a lot of upstream work so
I'm closing this bug as UPSTREAM. If you want to participate in this
work don't hesitate mailing firstname.lastname@example.org which is the place
where hal and fstab-sync development is carried out.
