On shutdown there is a message '/: device is busy'. I found out, that this is originated by the netfs-script in /etc/rc.d. It tries to umount everything on the network. By removing this hook the warning went away. I think this is not as meant. Its not a critical error, only a warning, because of that i would hear you opinion on that.
This is known. If you have ideas, they are welcome. I only tested whether NFS root works in general, but I never figured out all the small problems.
Additionally i discoverd following piece of code in rc.shutdown:
stat_busy "Unmounting Filesystems" /bin/umount -a -r -t noramfs,notmpfs,nosysfs,noproc,nodevtmpfs -O no_netdev stat_done
Here, only non-network filesystems are unmounted, right? So, an NFS-root is not unmounted on shutdown. That is not good, i think it should be looked for a solution.
You cannot unmount the root file system. It should remount it read-only at a later stage though. I don't think umounting is NFS even necessary, is there a problem when you don't?
What do you think? Would be nice to hear from you.
I'll accept any improvements in that area, but I never used NFS root with Arch for more than basic testing.
