I'm going to give CentOS one more try before trashing the LVM group.
I'm downloading the DVD for 4.2, so tomorrow when it finishes I'll
burn a DVD with it, and try a straight install, formatting everything
but the LVM group, and see if it works that time.
I'm wanting to stick with a Redhat like system, since the plans at
work are to upgrade from RHEL 2.1 to 4 in the next few months, and my
comfort level is to stick with a similar system at home. And until
this problem, I had been pretty happy with CentOS.
Obviously, at this point, I don't know if this is a problem with the
RHEL underpinnings, or whether it is in CentOS itself.
