Hello Steve,
on my running Ubuntu 9.04 PXE system, I got :
---------------------------------------------
$ cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'vol_id --uuid' to print the universally unique identifier for a
# device; this may be used with UUID= as a more robust way to name devices
# that works even if disks are added and removed. See fstab(5).

The same system booting Ubuntu 9.10, I got :
---------------------------------------------
$ cat fstab
# /etc/fstab: static file system information.
#
# Use 'blkid -o value -s UUID' to print the universally unique identifier
# for a device; this may be used with UUID= as a more robust way to name

The 'df' can't be done as like this system is not booting, he can go
further when booted in single user mode from TFTP server.
1) So when booting in normal mode the system is waiting indefinitively
with error :
-----------------------error------------------------
One or more of the mounts listed in /etc/fstab cannot yet be mounted:
(ESC for recovery shell)
/home:waiting fr hal9000:/home
modem-manager: Loaded plugin Gobi
blablabla
^C
mountall: Cancelled
still waiting and nothing more, the only thing I can do is a Ctrl+Alt+Del
:-(
----------------------error-------------------------
2) but booting in single user mode the system is going further, and
prupose to me the "Recovery Menu", I choose "resume", and then it comes to
the login prompt, I enter as root.
# df

!! Take care of the first df. it returns "rootfs" for /
Here are the params for TFTP server to boot the system :
--------------------------------------------------------
DEFAULT linux_good
PROMPT 1
TIMEOUT 100
LABEL linux_new
KERNEL vmlinuz-2.6.31-16-generic-pae
APPEND root=/dev/nfs initrd=initrd.img-2.6.31-16-generic-pae

LABEL linux_good

splash
The only thing changed on Ubuntu 9.10 is it detected 4GB and set the PAE
kernel.
# uname -a
Linux tron 2.6.31-16-generic-pae #52-Ubuntu SMP Thu Dec 3 23:18:13 UTC
2009 i686 GNU/Linux
#
I'm going to try to install the regular kernel as on ubuntu 9.04 to test
in case it works.
Cheers
Stephane
