RFC: new boot menu option: "boot using /etc/fstab/fstab.bak"

J

jb_fvwm2

As the title says (or similar).
I've modified fstab, accidentally putting 2 2
as the last parameters to a non-default-mounted
FS where it should have been 0 0
I discovered over two hours that only one of
the several live cd's could eventually mount the
root filesystem.

Today, I modified fstab putting "nodev" with
noexec, (man 8 mount, nodev is unknown) again
hosing the boot. (per a 2003 install writeup)
Code: 
mount -f /dev/ad1s2a /dev/fd
from a 6.0 live cd... and I could fix it.

Would this not make it much easier for
everyone to have the additional option? Then
backing up fstab could be one of the first
tasks upon a new install to make it a valid
menu choice.

Or some other way.

Yep, that's how everybody's doing it ;)

And in case / gets borked there's always the mountroot option.

Maybe I did not try it because the edit was
disallowed when the faulty fstab dropped to
single user "anyway" at boot. If single user
at the menu works, now I know. ( I seem to
recall "read-only filesystem" or some such
error today.)

Fsck the filesystem and remount using mount -u / and it's writable.
 
I put those instructions on the monitor right below
the CLI group that has
Code: 
swapon -a
as the third of five commands. Ready for use
next time it happens.
