Hello mek,
originally, muLinux supported NFS root. I tested it many times, in old
releases. The setup was setup/nfs, using NFS_ROOT capability.
Surely, in modern release this support is broken because a lot of files
changed theyr names: look in /etc/rc.prep-nfs to track the problem.
I'm uploading the 10r0 release a this moment, but nfs-root is
untouched, sorry.
The thing worked in this way: the user do setup/nfs using a floppy
muLinux; then "setup -s". When the floppy boot newly, it try to
mount its root via NFS, but first of all it load ethernet drivers.
Because in muLinux ethernet and PCMCIA are unified ( setup/eth0 and
setup/eth1 in 10r0; setup/network in 9r5), the problem isn't PCMCIA,
but the few filenames changed in /etc/rc.prep-nfs.
This is your actual /etc/rc.prep-nfs (9r5)
---------------------------------------------------------
#set -x
echo "Setting up nfsroot booting ..."
# load ethernet driver
#setup keymap
setup network
setup nfs
#setup -s
# load network parameters
. /setup/cnf/network.cnf
. /setup/cnf/nfs.cnf
. /setup/cnf/net.cnf
# set nfs-root parameters into kernel
echo $NFS_ROOT >/proc/sys/kernel/nfs-root-name
echo $IPADDR:$NFS_SERVER:$GATEWAY:$NETMASK:$HOSTNAME:$INTERFACE \
>/proc/sys/kernel/nfs-root-addrs
echo 255 >/proc/sys/kernel/real-root-dev
echo
echo -e "Mounting my root via ${BRIGHT}${CYAN}NFS${NORMAL} from $NFS_SERVER"
----------------------------------------------------------------------------
The row
. /setup/cnf/net.cnf
must be surely eliminated. In next release, you have to change
the core code in:
------------------------------------------------
# basic setup's
setup eth0
setup nfs
setup network
# load network parameters
. /setup/cnf/network.cnf
. /setup/cnf/nfs.cnf
. /setup/cnf/eth0.cnf
------------------------------------------------
The script rc.prep-nfs take place when /linuxrc is called, first of
mounting real-root.
After some test, I'm sure it will works. Good luck!
P.S. unfortunately, I read your post only *after* 10r0 official release.
Michele
