exactly. i think it's excellent to have for example:
rtk0, ex0, ex1, ex2 and know that it's first realtek NIC, first 3com nic,
second 3com nic etc...
the same with serial boards. it's nice to know that tty00, tty01 is 2
standard PC serials, for example 3,4 (as i hardwired) on my extra 2-port
PCI card etc...
on one linux server with 3 8-port PCI cards i do renaming/setserial to
make devices like:
/dev/ttyS0, S1 - standard 2 serials
/dev/P1/ - 8 ports on 1-st card
/dev/P2/ - 8 ports on 2-nd card
/dev/P3/ - 8 ports on 3-rd card
so when i connect new leased line modem on 3-rd connector of 2-nd card i
don't need to check what tty it is (and what tty it will be tomorrow ;)) i
just use /dev/P2/3

in linux you have eth*. and with 20 ethernet ports (5 4-port NICs) we
could say "what eth will it be today?" ;)
with netbsd it's JUST FINE (tm) :)
