I agree here. I think that easy to use rather then short is
much more helpful. We can even have things short! Something like:

/dev/ide0
/dev/ide1
/dev/ide2
/dev/ide3
...

or even (heaven forbid):

/dev/hda
/dev/hdb
/dev/hdc
/dev/hdd
...

And then have _additional_ links elsewhere such as:
/dev/disk/ide-disk0
/dev/cdrom/ide-cd0
/dev/tape/ide-tape0
/dev/floppy/ide-floppy0

or something.

If the user is supposed to figure out some coded form like
/dev/ic/b0l0p0q1n9

there had better be a _damn_ good reason. I don't consider there to
be such a a compelling reason for the ide bus, since the existing numbering
scheme /dev/hd[a-f] already uniquely identifies each device. If somebody
removes /dev/hdc, the device at /dev/hdb doesn't change.

The reason the scsi scheme is so wierd, convoluted, indecipherable, and
strange is that with the existing scsi interface, when you remove /dev/sr2
that /dev/sr1 was getting renamed.

Lets not impose a unnecessary but compatable "fix" for ide, since ide
doesn't have the problem that the fix was invented for. I say that we
use names that are human readable! I really don't want names that are
short and concise. devfs supports long filenames, right? Lets use them.
