Two issues - cdrom_id and duplicate /sys entries

[Robby Workman <rw@rlworkman.net>]

First, it seems that /lib/udev/cdrom_id is not exporting correct
information about the capabilities of optical media drives.
This system contains a Lite-On combo cd writer / dvd reader and
an NEC dvd writer drive, but the cdrom_id binary returns this for
each of them:

root@isotope:/lib/udev# ./cdrom_id --export /dev/sr{0,1,2,3}
ID_CDROM=1

See http://rlworkman.net/attr-walk/ for the udevinfo attribute
walks on each of the devices.

Of course, this brings up the second issue:  there are only two
optical drives in this box, and there are four devices created.
0 and 2 are essentially "mirrors" of one another, as are 1 and 3.
Interestingly enough, after dumping the udevinfo output to the
files linked above, sr1 and sr3 show different sizes, even though
they are the same drive.  A diff of the respective files shows a
few more things that are different, but none as strange as the
size difference... :/

bash-3.2$ grep size sr?-attributes
sr0-attributes:    ATTR{size}="2097151"
sr1-attributes:    ATTR{size}="4"
sr2-attributes:    ATTR{size}="2097151"
sr3-attributes:    ATTR{size}="9143552"

Ideas?  :)
