Re: [linux-lvm] Restricted partitions?

This one might be a problem.  (think: growing it, and it might
even end up on a different HD.)

Why 2 volumegroups, why not one that grows by appending the
(then free) space of /dev/hda?

/dev/vg01 is your new volume group, right?  I _think_ devfs
sees it accessed and tries to load the appropriate module
(none, but it doesn't know).

Both are on LVM here -- and if my system really needs /tmp it
can easily use /tmp -- which would be on / then ( /tmp is not mounted
then).  The only problem will be that after mounting those
you won't be able to access the files which are there, but on
the root partition.  But then mounting is a very early step
in the boot process, so that won't be a problem.

That would be my guess.
