[cheetahman]

Hello I have problems moving my edited fstab to overwrite the original fstab and i get the error

bash:/dev/null:Permission denied
knoppix:/#

while running the command
su
chroot /mnt/hda7/

I have also made my partition write but I get the errors

Access denied couldn't write to /mnt/hda7/eetc/fstab

Access denined to /mnt/hda7/eetc/fstab

Can you clarify what you're trying to do? Can you also post some more context of the commands that you're executing and their respective outputs? Thanks.

I am trying to edit the fstab with either Knoppix or Suse in maintence mode by overwriting the new fstab with the old one.

Yes i got 2 errors and tried to run Reiserfsck --fix-fixable

su
chroot /mnt/hda7/

he error I get is
bash:/dev/null:Permission denied
knoppix:/#

vi /etc/fstab

press i and edit, then press Esc, and then type :w so save and :q to exit, then restart the comp with Ctrl+D.

Got this error

--Insert-W10:Warning:Changing a reaonly file
E325:Attention

(1) Another person may be editing the file

(2)Edit session for this file crashes
In this case use :recovwer or vim -r /etc/fstab
to recover the changes if did this already delte swap file ?etc/.fstab.swp to avoid this message

E303 Unable to open swap file for "/etc/fstab",recovery impossible

E505:"/etc/fstab" is read-only (add ! to override)

I got this from posting on the Knoppix forum

Yes, just open a konsole in kde, paste it in and hit enter. Then when you type mount it should be listed as mounted. You might as well do sudo su in the konsole to become root so you can edit the file with mcedit /mnt/hda7/path/to/filename . Ctrl-d gets you out of su

I tried

sudo su
then cd etc/fstab
then mcedit fstab
and I could edit it but couldn't save it and get the error

Save As
Cannot save file
