Dear all,

when i do
# mount -treiserfs -o acl /dev/sda9 /home/
mount: wrong fs type, bad option, bad superblock on /dev/sda9,
       or too many mounted file systems

So I tried:
# mount /home
mount: wrong fs type, bad option, bad superblock on /dev/sda9,
       or too many mounted file systems

# grep sda9 /etc/fstab
/dev/sda9            /home                reiserfs   
defaults,noatime,acl          1 2

# mount /dev/sda9 /home
-> successs

# uname -a
Linux zibsrv34 2.4.19-4GB #1 Fri Sep 13 13:14:56 UTC 2002 i686 unknown

It is a default SuSE kernel. I cannot update at now, couse I have a 
IDE-Raid with binary only driver.
