Perfect. Thank you; that does exactly what I want for
my removables and autofs handles the rarely-used
partitions fine. Perfect all around.

Agree, automoun is fine. A short timeout for CD's work fine. Set the timeout 
to 15 seconds. Shorter is bad if you tend to use GUI's that don't hold a lock 
on the CD, as the CD will often be unounted/remounted (=slow) inbetween the 
clicks. and all you have to do is wait a few seconds before the disk is 
ejected. If it doesn't come out someone is using it.

Note that any time your filesystem is unmounted you throw away the cache.

Trapping eject button on CD-ROM

[Jon Niehof]

Apologies if this has been asked before; I read a
HOWTO that seemed to imply it was possible but haven't
seen anything beyond that.

Is it possible to configure autofs to "catch" the
eject button on a CD-ROM and unmount the filesystem
(presuming it's not busy, of course), then eject?

No.

If you monitor insert and eject you don't want autofs anyway.  You want 
something like what Solaris calls "vold".
