X-BeenThere: tuhs@minnie.tuhs.org X-Mailman-Version: 2.1.26 Precedence: list List-Id: The Unix Heritage Society mailing list List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: The Eunuchs Hysterical Society Errors-To: tuhs-bounces@minnie.tuhs.org Sender: "TUHS" A couple of Cambridge quota-related anecdotes: In its early days the Debian bug tracker was run out of Ian Jackson's personal account on our central Unix service. He had to delete bugs when they were closed to keep within his disk quota. Our mail software Exim has a two-level quota system: it handles quota errors from the OS as a hard limit, with some annoying portability hacks https://github.com/Exim/exim/blob/master/src/src/transports/appendfile.c#L1208 Exim it also has its own per-mailbox quota implementation. This can help control memory usage (mainly by Pine, back in the day...) as well as providing soft limit warnings and other bells and whistles.
