Rescue a broken fstab from busybox with no live CD?

[mrule]

Hi all,

I had a drive mounted from fstab that failed. It's not an important drive, but the system drops into busybox anyway when it notices that it's missing. I can mount the root drive, but ubuntu's busybox version doesn't seem to contain a text editor, so I can't comment out the dead drive from fstab. I don't have a live CD and I don't have means to create one.

I feel like this should be quite solvable. All the system needs to do is skip mounting the missing drive and everything will be fine. I just can't for the life of me find information about how to accomplish this from busybox.

Ok, so here is the update. It may well be that the version of busybox built for ubuntu simply isn't set up for making repairs -- because most people are expected to use the liveCD? Anyway I went out and got a USB stick and used that to fix things up.
In the future, as I understand it, I should specify "nobootwait" option in fstab for non-essential drives.
