we only log metadata. Running reiserfsck might get your data back
though (or it might not, depending on whether your old data got
overwritten.)

Yes, but (not butt =) if you have done some other file operations after the
delete, your deleted file might have been overwritten by another file.
Especially if you have little free space on your hard disk.

Yep but ( ;) 80% situations is like "ups i deleted it" and undeletion
operation is taken straight after that. So it would be nice to have it...
Just a sugestion...

yes, it would be nice, and patches to create a /..graves (notice the
copyright avoidance naming scheme, and the opportunity for the gui guys
to have some fun) will be accepted by me (though whether they will get
past Linus I don't know, I think he prefers that libc do it, so I
suggest making it a patch to libc.)
