[Yum] Removable media support in yum

[seth vidal]

Suggestion:
  If you're going to send patches with new features - make the patches
for HEAD, not for 2.0.X - this feature, if it were to get in this form
AT ALL would not get in to 2.0.X.

With regard to the actual patch:

 you just eject the cdrom w/o asking - that could have negative effects
if a user was not expecting it. Why not just prompt the user and let
them prepare the next media - that way you're not bound to cdrom/dvd. If
someone is loading the units off of compact flash or floppy disk or zip
drive, then the code would be more generic and more well-suited to them.

Also - why not have yum-arch take multiple disks when you tell it to
talk to removable media? Then you can have 1 repository for all N disks.
So the header.info ends up looking like:

0:name-1.1-1.i386=DISKLABEL/path/to/name-1.1-1.i386.rpm

then have tag the repo as removable in yum.conf

[redhat9fromcd]
name = Red Hat Linux 9 from CD
baseurl=removable:///mnt/cdrom/

Then have it look at the disklabel - if it is not the one it needs then
it asks for a new disk.

If all the disklabels are the same then you have a problem, clearly, but
then so does your vendor :-D
