In case of devfs, only those who are actually installed take up space
in /dev. Is that still problem? (I would not like to have /dev
multi-directory, because it would make manual looking for devices
harder (by one or more chdirs).) Hmmmm. Thinking about sunsite. That
is I believe something like 50 scsi discs, and you probably have about
2 devices per disc (h...lL and h...lLpP), that's about 100 entries,
which is perfectly ok. I think that even 1000 discs would be ok
(altrough not good), since entries are in RAM and readdirs are not
done too much, anyway.
