Hi!

I have diskless (or rather - rootless - I want to share the same root file system with many exactly the same computers - only home is rw, and of course some others - please take a look) station which is booted by pxe. It starts ok, but when I run:
Code:
mount

I see root partition is mounted with some strange parameters:
Code:

rootfs on / type rootfs (rw)
/dev/root on / type nfs (ro,vers=2,rsize=4096,wsize=4096,hard,nolock,proto=udp,timeo=11,retrans=2,sec=sys,addr=192.168.1.19)
proc on /proc type proc (rw,nosuid,nodev,noexec)
sysfs on /sys type sysfs (rw,nosuid,nodev,noexec)
udev on /dev type tmpfs (rw,nosuid)
devpts on /dev/pts type devpts (rw,nosuid,noexec)
shm on /dev/shm type tmpfs (rw,nosuid,nodev,noexec)
/dev/sda5 on /var type reiserfs (rw,noatime)
tmpfs on /tmp type tmpfs (rw)
tmpfs on /root type tmpfs (rw)
usbfs on /proc/bus/usb type usbfs (rw,nosuid,noexec)
192.168.64.1:/home on /home type nfs (rw,noatime,vers=3,rsize=32768,wsize=32768,hard,proto=tcp,timeo=600,retrans=2,sec=sys,addr=192.168.64.1)

(I have two ethernet cards and two "networks" - one is 192.168.1.x and second is 192.168.64.x - so this is ok).
It looks very strange for me. I need locking and I want to use newer version of nfs, maybe also increase rsize (wsize not needed - this is read only...).
This is my pxelinux.cfg/default file:
Code:

DEFAULT kernel-devel-x86-2.6.23-gentoo-r3
APPEND ip=dhcp root=/dev/nfs ro nfsroot=192.168.1.19:/var/diskless/devel


And this is my fstab file:
Code:

192.168.1.19:/var/diskless/devel /              nfs     noauto,ro,async,rsize=16384     0 0
192.168.64.1:/home               /home          nfs     defaults,noatime,async,rsize=32768,wsize=32768  0 0
proc            /proc           proc            defaults        0 0
shm             /dev/shm        tmpfs           nodev,nosuid,noexec     0 0
/dev/sda5       /var            reiserfs        defaults,noatime        0 0
tmpfs           /tmp            tmpfs           rw      0 0
tmpfs           /root           tmpfs           rw      0 0

What should I do?

Any ideas?

Regards
L.
