ok, you asked for it ;)
there is still some idiosyncrasye wrt HSM and it doesn't build.
*joking*
2.2.11 or 2.2.12 does not seem to be a big problem to me.

i believe useful integrating raid and lvm
it means a user can dcide the different raid policy
for each type of data.
eg. striping for /var/spool/junk
3 way raid1 for /very/important/stuff
raid5 for /other/data

Leaving things as now is still very useful, and i will be very 
happy to have this arrangement finalized.
we really need to fix LILO (or another boot loader, grub already
can read ext2 filesystems) to be able to understand raid and lvm.

as a side question, how does LVM autodetect works
(if it exists, that is)?
