[Pkg-ltsp-devel] Which filesystem on initrd

[Marcin Kuk]

I have problem

Distro: Debian etch (2006.08.22 upgreaded)
# ltsp-build-client (OK)
# ltsp-update-kernels (OK)
# ltsp-update-sshkeys (OK)

DHCP: settings correct.
NFS:
# cat /etc/exports
/opt/ltsp                 192.168.1.0/255.255.255.0(ro,no_root_squash,sync)

On client:
...
pivot_root: pivot_root: No such file or directory
...

So I would like to view initrd.img if pivot_root is called from NFS or "ramdisk"

# file initrd.img-2.6.16-2-486
initrd.img-2.6.16-2-486: gzip compressed data, from Unix, max compression
# mv initrd.img-2.6.16-2-486 initrd.img-2.6.16-2-486.gz
# gunzip initrd.img-2.6.16-2-486.gz
# mkdir initrd_loop
# mount -o loop initrd.img-2.6.16-2-486  initrd_loop/
ioctl: LOOP_CLR_FD: Urządzenie lub zasoby zajęte (polish locales:
device or resources are busy)
mount: you must specify the filesystem type
# file initrd.img-2.6.16-2-486
initrd.img-2.6.16-2-486: ASCII cpio archive (SVR4 with no CRC)

Which filesystem I should use?
Earlier it was minix, ext2, cramfs as I remember.
