Is there a way to "set" a particular device to a particular

You certainly mount a device on a partcular mount point but what would
you expect: man devlabel
to return?
Alexandre was suggesting you view the man page for "devlabel" by
entering the command "man devlabel".
devlabel creates a symbolic link between the physical device and a
mnemonic name (sort of like the way "/dev/cdrom" points at "/dev/hdb"
or whatever). It also reads the UUID from the device if it has one (it
creates one otherwise) and puts an entry in the /etc/sysconfig/devlabel
file that it can use later to recreate the symbolic link if the device
name changes (such as would happen if the USB bus changes).
For example, my 750MB USB Zip drive is sometimes /dev/sda and sometimes
/dev/sdb (depending on if my USB FLASH is plugged in). devlabel has
created a /dev/zip750 mnemonic name for me which is a symlink to either
/dev/sda or /dev/sdb, depending on what the bus looks like.
In the /etc/sysconfig/devtable file, the current link is shown along
with the UUID "S:IOMEGAZIP750", which devlabel can use to find the
device on the next boot. Regardless of how my stuff is set up, I can
always mount my Zip drive by "mount /dev/zip750 /mnt/zip".
Does that help?
