sure. I hope I can be of help.

the desktop is ubuntu 7.10, using pam-scripts we create smb.cred and
run through a text file ~/.shares that reads server:share
server:share, etc
mount -t cifs //$server/$share $mountpoint -o
iocharset=utf8,credentials=$CRED_DIR/smb.cred

both samba servers are debian etch's.

The desktop box is diskless booting with live-initramfs. the root
filesystem is a union of ram and nfs. /home is mounted onto that from
another nfs server.
/ (union de nfs and ram)
/home (nfs mount)
/home/user/share/mount1 (cifs mount).

for some reason, /home isn't present in /etc/mtab (although it is in
/proc/mounts)

Reading somwhere these days I saw something about nautilus and mtab,
so thinking this might be the problem I have also tested mounting the
shares on /tmp (because /tmp is present in mtab).

/tmp/user/shares/mount1
/tmp/user/shares/mount2
/tmp/user/shares/remote_server/mount3

So, there are some cifs mounts on the /tmp directory and _no_ cifs
mounts on my home directory  (no softlinks to the shares on /tmp
either) . Now when I open nautilus at my home, I can see network
traffic to the samba servers!! That has taken me by suprise. It seems
Nautilus is doing something like
# ls -laR /

After getting correct results with pcmanfs, I've also tried thunar. No
problem there either.

What's the next step?

Cheers.
Chris.
