The output of ‘mount’ should contain the file system, for example: /dev/sda1 on /boot type ext3 (rw,noatime,errors=continue,commit=5,barrier=1,data=writeback) /dev/mapper/ares0-root on / type ext4 (rw,noatime,errors=remount-ro,user_xattr,acl,barrier=1,data=ordered) ^^^^ Best regards, Claudius -- <woot> Put *that* in you .sig and smoke it, Knghtbrd. <Culus> You know he will read this :> <woot> heheheheh. http://chubig.net telnet nightfall.org 4242
