Correct, that’s a udev thingy. Here is a nice FAQ:
http://www.kernel.org/pub/linux/utils/kernel/hotplug/udev-FAQ

You could potentially do likewise with devlabel, although I've never
tried for a tape library.

Oh here we go - Flamefest 2006 :-0 
I think udev is only in RHEL5, but I've never checked.

You can upgrade for "free" to RHEL4 with the same RHN subscription
number / login as that for RHEL2.1 / RHEL3 / 4 / 5 and so on. (Mail me
for details)

I like debian, who doesn't? But I still use RHEL on enterprise
deployments. 
Its kinda a work thingy.

Fedora is RHEL's testing ground. Once things stop blowing up, it goes
into RHEL after 6 months of stability (need to check that). 

There are plenty of other things that are not their either.

Example: ACPI power off - among other cool things we take for granted. 
That’s not to say you cannot hack something together to do the same job
- not for everyone though - support 'might' be an issue there.
