I think you are wrong; I seem to recall a 2.1 for 390 and a 2.1 beta for
390x.
I also think that was a 2.2 kernel. Long may it RIP.

LVM is what partitioning always wanted to be when it grew up.
I strongly recomment that people use LVM instead of partitioning.
But remember: both partitioning and LVM effect the layering of a
crude filesystem below your "real" filesystems. (yet another layer)
So sometimes you might want to use ne

I'll chime in here, RHEL 3 on s390 was not pretty. I highly suggest you go
to at least RHEL 4, the later the better (4.7 is the latest); if possible go

Also just a note
You need to use at least RHEL4.6 to install layer2 rh. There's a bug
in pripy released that does not recognize layer2 in anaconda. 4.6
