Here is a patch against the current subversion repository, that makes
udhcpc have an adjustable timeout. Works for both foreground and before
it drops to the background. This brings it more in-line with ISC dhcpc.
Use like so:
udhcpc --timeout=10 ...
or
udhcpc -T 10 ...
Still shooting for 1.1.1 this month? Would really be great if you could
get this in that release.
