indeed. i really like it, overall.

oh well...

i just tried initramfs-tools 0.69b from etch, and nfsmount appears to
work fine for ltsp. we had enabled a workaround to use mount instead for
the ltsp packages, but that appears to be unnecessary with recent klibc
nfsmount.

and, from my breif and initial tests, it seems the nfsmount in sid is
also working, so maybe switching scripts/nfs to use nfsmount, as long as
you're planning on keeping nfsmount around... (and making it a variable,
so easier to enable a workaround... there's a patch for this in my bzr
branch mentioned below)

maybe also/alternately getting NFS support for busybox mount is also an
option, if we can nudge the busybox maintainers? (#348664: busybox:
consider CONFIG_NFSMOUNT).

all that said, i must say, i'm partial to regular old mount :)

my initramfs-tools bzr branch:

http://llama.freegeek.org/~vagrant/bzr-archives/initramfs-tools/vagrant-initramfs-tools

currently should contain a patch to make the NFS mount command a
variable, and defaulting to nfsmount, as well as (incomplete but
useable) patches for #380649.

soon to be more :)

the full qemu (0.8.1-1) commandline i use is this:

qemu -hda /dev/zero -m 80 -kernel /opt/ltsp/i386/boot/vmlinuz \
  -initrd /opt/ltsp/i386/boot/initrd.img \
  -append "nfsroot=10.0.2.2:/opt/ltsp/i386 root=/dev/nfs ip=dhcp console=ttyS0,38400" \
  -nographic 

i've also tried without the console=ttyS0,38400 and -nographic parts.

/opt/ltsp/i386 is populated using ltsp-server from current development
branches.

thanks!

right... well, nfsmount seems to be working now, and making it
configurable will greatly simplify workarounds in the future(hopefully
not needed)...

live well,
