where would i configure an external HD to be automounted?
more specifically, on an old lenny system, when an external maxtor (1-touch) HD was plugged in via USB, it was *apparently* mounted automatically under /mnt/maxtor, for the purposes of backups later in the evening. i have a full backup of /etc from that old system, and i'm trying to figure out where that would have been configured so i can add it to the new system. i've checked things related to autofs but i don't see it. hint? i'm sure it's obvious, i just haven't found it yet. rday -- Robert P.

The way it works is, you plug in the disk, and access the mount point. When you try to access the mount point, it checks for the disk and mounts it. Also, after a time you specify (say one minute, for example), for which the disk is not accessed, it is automatically unmounted. So, you can safely plug it out. There are too many tutorials and documents to mention, so just search, and you'll find plenty of direcitons. HTH.
