I've done some work within the framework of klibc and initramfs to replace the in-kernel ipconfig and nfsroot code. A snapshot of the klibc CVS tree is available at:
http://www.speakeasy.org/~bos/klibc-20020505.tar.bz2
This contains a klibc tree that builds against 2.5.68 and 2.5.69 (at least on x86), along with three programs of interest:
* ipconfig was written by Russell King several months ago. I've removed bit rot from the code and made some changes so that it handles both DHCP and static configuration. * nfsmount is a filesystem mounter for NFS v2 and v3, UDP and TCP. Tested only against Linux servers so far. * kinit is a single statically-linked binary that incorporates both ipconfig and nfsmount, and which can be dropped into an initramfs filesystem for use as /sbin/init. It parses /proc/cmdline for "ip=" and "nfsroot=" sections, performs IP configuration, NFS mounting, and finally does a pivot_root to the freshly-mounted filesystem.
I don't yet have quite enough hardware handy to be able to test the last 10 lines of code in kinit without substantial inconvenience, but It Should Work (TM).
If you're interested in kicking the tyres and ironing out problems, you may want to subscribe to the klibc mailing list so that HPA and others can see what's going on:

Otherwise, please send problem reports to me directly.
