In my particular case, yes. I like to know beforehand where they are mounted. AFAIK hotplug or its successor mounts them where it wants to ?

I think "LABEL" would take precedence over another mount option (UUID, ID or PATH) so if you "tag" your media device with a LABEL, it should be mounted when plugged under "/media/mylabel".

If fsck returns with error code greater than 1, the boot process stops at a prompt to enter root password or control-d. My argument is that the boot process should not even try to run fsck on a non-existent device.

Error code 1 on fsck gets an error logged, but doesn't stop the boot process. Upgrading dosfstools past 3.0.1 caused an error code greater than 1, which triggers the stop of the boot process. I don't understand why initscripts tries to fsck a non-existent device. Maybe I should file a bug against initscripts. I had initially filed a bug against dosfstools but had no response: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=562536 I would just like to have USB flash drives that may or may not be plugged into machines that aren't switched on all the time, and I would like them to be mounted if they're plugged in when the machine is powered on, and for the machine to boot anyway if the USB flash drive is not present.
