From J.S. Moore on Wed, 26 Aug 1998
(An old AG that I never answered)
The manpages indicate that a file with the u option set is undeleteable, but it doesn't say how.
Any ideas? J.S. Moore
I think this bit was reserved for future use and that it would/will require a userspace program (or use of an API by programs like 'mc' and other file managers) to actually browse and recover "deleted" files.
I think the current feeling in the development community is to implement a new filesystem or some new extensions to ext2 that would allow full versioning support. However, I don't know the real skinny on it.
