Scyld & Ramdisk

When I install Scyld, it initially uses Ramdisk for the / partition. I
used beofdisk to create the two default partitions (a 2 gig swap and the
rest /). My /etc/beowulf/fstab reads as follows:
# This is the default setup from beofdisk, once you setup your disks.
/dev/hda2 swap swap defaults 0 0
/dev/hda3 / ext2 defaults 0 0
# These should always be added
none /proc proc defaults 0 0
none /dev/pts devpts gid=5,mode=620 0 0
# NFS (for example and default friendliness)
192.168.1.1:/home /home nfs defaults 0 0
According to beostatus (and bpsh 0 free -m) I was using 64MB out of 1011MB
of memory before I changed fstab. After I changed fstab, I was using
370MB out of 1011MB. Why the sudden increase? bpsh 0 df -m shows little
disk space being used. bpsh 0 ps -ef shows few processes running.
Also, just a side note: Why doesn't the default kernel of Scyld include
Ramdisk support? I couldn't boot my nodes until I recompiled the kernel.
After that, how do you install bproc via rpm? If I just reinstalled the
rpms via 'rpm -Uvh --force', then I got error messages when trying to run
bpsh (and others). I had to download the tar file and install that.
P.S. Is there a more appropriate place for me to send this? I don't want
to abuse this list as a Scyld support line.
