i know that
and i didn't mention anything about / ( my / is normal partition )
the thing is that mkinitrd checks only for /etc/raidtab and not for
/proc/mdstat
so it doesn't add the raid modules and thats the cause for missing PV's
( raids) and VG's
after installing ( and booting ) the 2.4.18-1mdk i had no raid and lvm
devices
and i had empty /proc/mdstat and /proc/lvm/global
that's what i have with raid compiled in
