chattr -V +u < file >

This command set the attribute u (Undeletable), only the root and the owner file can delete the file.

That is very interesting. What filesystems support the u attribute, or is it generic to all Linux FS that support EAs? Is it accessible via libacl.so, or only libattr.so? Is there a way to make Samba map this to the appropriate SMB attribute? Greg -- Greg Freemyer
