# Argh! dhclient in FreeBSD 5 has a new auto-background "feature",
# it dives into the background after 10 seconds regardless of whether
# it has received a response.  This is fubar for us.  Unfortunately,
# we cannot just crank this number through the roof because it is based
# on a polling interval which actually has a rational purpose.  The timeout
# is actually (2 * polling_interval) where polling_interval is how often
# dhclient rechecks an interface without link.  We need to keep this value
# reasonable in the event that we boot up and don't immediately have link
# on the control net.  So lets try 15 seconds (30 second auto-background
# timeout) and see how things go.

but "prepare" is the script that goes in the tftpboot directory on boss.

grotesque dhcp-on-all-interfaces hacks :-)

standard scripts.  The current FreeBSD 5 image uses this.

possible to:

	gmake client
	sudo gmake client-install

on a FBSD4, FBSD5, RHL7.3, and RHL9.0 client node.

There are still some dependencies that are not explicit and which would
prevent a build/install from working on a "clean" OS.  Two that I know of are:
you must install our version of the elvin libraries and you must install boost.

- have pump/dhclient script record the DHCP'ed interface in
  /var/emulab/boot/control_interface

- change control_interface script to first check for that file
  and use the contents if it exists

Note that, as of this commit, we are still telling pump/dhclient which
interface to DHCP on (i.e., we still determine the control net interface
the old way to invoke pump/dhclient) so this commit is not that useful.

What still has to be done is to change the startup to invoke dhclient/pump
on all interfaces.  This turns out to be a royal, royal PITA.

Stay tuned...

1. "make clean" will just remove stuff built in the process of a regular build
2. "make distclean" will also clean out configure generated files.

This is how it was always supposed to be, there was just some bitrot.
