Speaking of /dev... Is there any method for safely removing the unused /dev
entries?

For example, my notebook does not have scsi, nor will it ever have one. I
also always mount floppies on fd0a, so fd0b, fd0c, etc are not used.

I'm just worried about breaking some unknown system component that depends
on some obsucre entry.

It won't tell you anything about the device file. It will only say the
device is there.

The first CD is cd0. You'll therefore have a /dev/cd0[ad] and
/dev/rcd0[ad] on most PCs.

ls'ing /dev/ is your best bet on a lot of this, along with section 4
of the man page. dmesg is useful for telling you that a device is present.

I'd recommend against that, for a variety of reasons including the
fact that you want the raw device sometimes and the block device at
others, and that you probably don't want to encourage a lack of memory
about what the file is actually called.
