Details

udhcpc negotiates a DHCP lease and calls action scripts after. It is called by rc.net and accesses:
This is a symlink to a multicall binary also containing udhcpd (lincmd) so these files cover both:

/etc/udhcpd.conf
/usr/share/udhcpc/default.script
/var/lib/misc/udhcpd.leases
/var/run/udhcpd.pid
/var/tmp/udhcpd.delta

Note that fw 1.63 (2004-05-03) is the oldest known firmware, which maybe never was used in the wild.
It is compeletly based on the AR7RD 2MB Flash / 8MB RAM reference design and its SDK from TI, with some adaption by AVM.
It already contained our well known CGI programs webcm and firmwarecfg and it already handled configuration in UI-Modules.
The beginning of FRITZ!OS could be considered the birth of ctlmgr, dsld and igdd in the second oldest fw 1.120 (2004-07-26).
The next important milestone was the birth of multid in fw 1.133 (2004-09-21). 4 important months in the history of FRITZ!OS.

Development of the udhcp package containing udhcpc was stopped with version 0.9.8 (2002-10-31).
It was included into busybox instead and development continued there.

See also the udhcp homepage and the busybox version udhcpc (bbcmd), which never was used in FRITZ!OS.
See also the latest original udhcpc(8) and udhcpd.conf(5) man pages.

Fw 1.63 help:

This is a symlink to a multicall binary also containing udhcpd (lincmd) so this help covers both (note the udhcpCD name):
