In my opinion, if you have another computer on the LAN with enough

other file system) is the following:
Pretty good timing, today I'm moving my Pismo to XFS. :) Thanks a load Colin!
1) Install system normally (be sure to install xfsprogs). The only
required separate partitions are /boot and /, although you can make
others if you want.
2) Make a netboot and NFS-root capable kernel (this means enabling
CONFIG_IP_PNP and CONFIG_ROOT_NFS). Install it. (You probably
want to use kernel-package for this).
3) set up yaboot to boot that kernel. Here's the relevant portion of
my /etc/yaboot.conf:
image=vmlinux
label=linuxnfs
root=/dev/nfs
append="nfsroot=192.168.5.76:/backup/space-ghost
ip=192.168.5.90:192.168.5.76:192.168.5.1:255.255.255.0:space-ghost:eth0:off"
read-only
Read /usr/src/linux/Documentation/nfsroot.txt for an explanation of
the options.
4) rsync -ave ssh --exclude /proc / [EMAIL PROTECTED]:/export/
I am using: rsync -arHpogDtxz -e ssh ... This preserves hardlinks, ownerships,
permissions and timestamps and doesn't cross filesystem boundaries. The latter
may not work with separate partitions for /usr and whatnot.
This probably doesn't matter too much after a fresh install, but my filesystem
is 8 gigs...
5) reboot using that kernel. You should now be running almost
entirely off the network (except for /boot).
6) use mkfs.xfs on /dev/hdX, mount /dev/hdX /mnt/image
I've had to edit /etc/mtab to make mkfs.xfs believe that it can actually
safely create the filesystem.
7) rsync -ave ssh [EMAIL PROTECTED]:/export /mnt/image
8) reboot using your shiny new XFS filesystem
Hopefully in about an hour...
