Comment 51 for bug 439604

If you had set 'bootwait=true', that's a syntax error; the correct option is simply 'bootwait'.

It's also entirely redundant on the / and /home filesystems. I've heard other reports that setting 'bootwait' on a filesystem where it's already implicit does cause hangs. This is a bug that should be fixed, certainly, but it doesn't mean that bootwait is unusable - there's no reason you should have set bootwait on these fstab entries in the first place.

I guess the original problem you were trying to solve was the issue described at <https://bugs.launchpad.net/ubuntu/+source/mountall/+bug/439604/comments/25>. I think that was indeed an fsck holding up X. And I agree that there should be documentation somewhere of the set of filesystems that mountall implicitly waits for.
