Yes. I have done "chmod" and a commit, but it didn't take. You have to 
also update the timestamp.

However, tla does check to see if files have actually changed. It *only* 
commits their changes, (it does a diff against the earlier version).

So yes to both questions.

If you were using hard-linked trees, you need to get rid of the revlib 
and get it new so that it has the right permissions. But remember, the 
trees are only hardlinked if you used "get --link" or "changes --link". 
If you didn't purposefully link them, then they are not linked.

Also, I *think* that if you touch a hardlinked file, it will change the 
revlib enough that it will notice, and consider itself corrupted. 
Definitely if you actually change the file, I've had some small problems 
with permissions, but tla has always recognized actual file 
changes/corruption of the revlib.
