I have used RedHat 6.2-FC3 and have NEVER had Disk Druid (or
equivillant) for
use AFTER installation. Suse has Yast which works when running the
system,
and Mandrake has DiskDrak, but RedHat doesn't have anything but fdisk!
WHY????????
fdisk is not difficult - and there is a webmin module for fdisk.
There is also qt-parted in pre-extras - which I believe is a GUI front end to parted, which (I think) is what anaconda uses.
