The managerpm module used to be distributed in a separate package.
This module is pretty needed by everyone using RPMs. If you had already
the independent module installed, remove it before upgrading
The fix for partition probing on rh6.1 was temporary. It was scanning
a fixed devices set (hda, hdb, ...). It now uses /proc/partitions to
find out which devices are available and create the fdisk command line.
fdisk is still used to probe partition because some information is missing
from /proc/partitions (the partition type for one).
There was a fairly old bug with IP aliases on kernel 2.2. When one
IP alias definition was changed, Linuxconf would end up changing
the alias in a strange way, cycling through the available alias
numbers (sort of).
