The file is /sys/contrib/softupdates/README.

(Also available at: http://lxr.linux.no/freebsd/source/contrib/softupdates/

Here is the specific text that talks about modifying /etc/rc:

156 Kernel Changes
157 
158 There are two new changes to the kernel functionality that are not
159 contained in in the soft update files. The first is a `trickle
160 sync' facility running in the kernel as process 3.  This trickle
161 sync process replaces the traditional `update' program (which should
162 be commented out of the /etc/rc startup script).

	.

	.

239 Operation
240 
241 Once you have booted a kernel that incorporates the soft update
242 code and installed the updated utilities, do the following:
243 
244 1) Comment out the update program in /etc/rc.
245 
246 2) Run `tunefs -n enable' on one or more test filesystems.
247 
248 3) Mount these filesystems and then type `mount' to ensure that
249    they have been enabled for soft updates.
250 
251 4) Copy the test directory to a softdep filesystem, chdir into
252    it and run `./doit'. You may want to check out each of the
253    three subtests individually first: doit1 - andrew benchmarks,
254    doit2 - copy and removal of /etc, doit3 - find from /.
