Re: undeletion at filesystem level or in extra filesystem?

[Roland McGrath]

Marcus used the term "undeletion" but brought up the common feature of
desktop systems that one might better call "delayed deletion" (there isn't
a canonical term I can think of).  Traditionally "undeletion" has usually
referred to half-assed recovery techniques that don't necessarily work, but
are intended to recover a file after you actually deleted it on disk.  I
think Thomas is reacting to what such "undeletion" mechanisms have been
like, while Marcus was really talking about a different interface feature
that has robust semantics.
