the problem i see with detach is the "utility" of the command.

example: my digital photo recorder.
i have an attach script to mount automatically the partition on the
cooresponding umass/da device. works great, and this helps.

but when detaching, the umount part should be done BEFORE detaching, not
after. i can't find any good use for the detach hook. most of things
should have been done before detaching, and i can't see how to do it
without user interactivity, thus avoiding use of the detach hook.

i once included a umount -f in the detach hook. after unplugin' the
device, it resulted in a panic. i don't remember if the umount was
causing it or if it was right after, when accessing the mount point or
repluging the digital recorder. anyway, i learned that umount -f is not
meant to be used often... perhaps not on top of usb. for now.

i manually umount the device before unpluging it.

my 2 cents...
