Hi all,
i've built my own kernel and image for our development system, and i've
been mounting the rootfs image over NFS.
the kernel successfully does dhcp before mounting the NFS share - then
udhcpc kicks in because the busybox-udhcp script looks for 'ip=dhcp' in
the kernel command line (/proc/cmdline), launching udhcpc if it's
present. does this seem odd to anyone?
AFAIK ip=dhcp is only really used for NFS root mounts, and i guess i
assumed that the kernel would also be responsible for maintaining the
DHCP lease. I might be wrong there.

If anyone can shed some light on this, that'd be cool.
Cheers,
Tim
