There seems to be some problem with mounted volumes on mounted
volumes with nfs-kernel.

I just switched from user to kernel.

this is my fstab on the server:

proc            /proc           proc    defaults        0       0
/dev/sda3       /               ext3    defaults,errors=remount-ro
0       1 /dev/sda1       /boot           ext3    defaults
0       2 /dev/sda6       /home           ext3    defaults
0       2 /dev/sda5       /mnt            ext3    defaults
0       2 /dev/sda2       none            swap    sw
0       0 /dev/hde        /media/cdrom0   iso9660 ro,user,noauto
0       0 /dev/fd0        /media/floppy0  auto    rw,user,noauto
0       0

/dev/hdf1       /mnt/kerberos/public/exchange   ext3
defaults        0
0 /dev/hdf2       /mnt/kerberos/public/main       ext3
defaults        0       0

this is my exports
/mnt/kerberos *.webthatworks.it(rw,no_root_squash,sync)
/home/ivan/Documents/kerberos
*.webthatworks.it(rw,no_root_squash,sync) /home/grace/Documents/kerberos
*.webthatworks.it(rw,no_root_squash,sync)

/mnt/kerberos contains
/mnt/kerberos/public
/mnt/kerberos/otherstuff
/mnt/kerberos/public/exchange
/mnt/kerberos/public/main

from the client I can see
/mnt/kerberos/public/exchange
/mnt/kerberos/public/main

but not their content

while
/mnt/kerberos/public
/mnt/kerberos/otherstuff
works as expected.

no problem with the user space nfs.

No relevant data in server logs... just start/stopping/unmounting
