Perhaps it should be a hard link instead then? Unfortunately, then you don't have the easy access to the information of what the link points to. > >> You have to shutdown cleanly, otherwise you lose DB. > > Sweet jesus. Talk about brittle solutions... The "DB" (whether it's an actual database, or a file on a filesystem, or whatever) shouldn't care about clean shutdown most of the time, only if you happen to crash in the middle of changing things. The contents and permissions of /dev aren't going to be changing much in most normal operation so it seems like optimizing the "DB" to be in a safe state most of the time, even if it makes changes slower, would solved this problem. eric
