MAC addresses, hostnames, and DHCP

[Thomas Charron]

  Is it out of the question to always give the host the same IP, if it comes
from MAC A or MAC B?

  It may cause some funny issues for a few seconds if, say, they unplugged
one MAC and plugged in another.

  Hrm, that could get ugly if they ever plugged BOTH in, wouldn't it..  DHCP
release/renew/release/ad nauseum.

  Why not assign the IP based on the machine name, instead of the MAC
address?  Windows provides it in the DHCP request automagically, but most
Linux installs need to have dhcpcd tweaked to provide it in the request.
