Ok, I make myself perfectly clear:
I'm running a fileserver and want to implement something like 'salvage' from Novell. This utility lets you undelete files that have been deleted before. Therefore, I need this not only for 'samba', but for 'nwserv', 'rm', 'ftp' etc.
Also, I'm not only fixed to ext2, because I allow mounting MS-DOS formatted disks, HFS formatted disks etc.
So I think of a 'layer' between the kernel and any filesystem that modifies just 'unlink' commands.
There is something like this with 'secure/encrypted' filesystems. The only reason for my mail was to find out if something like this does already exist.
