Hello I am new in linux. My problem is that my changes in /etc/fstab put back after a reboot.

If i make following changes:

/dev/hda2 /mnt/hda2 ext2 noauto,users,exec 0 0
(orginal)

/dev/hda2 /mnt/hda2 vfat noauto,users,exec,usermask=000 0 0
(the changed version)

With this change i can mount my Fat32 partition. But if i make a reboot all the changes put back.

What can i make?
