The makefile is generated by "makerc" (conceptually similar to "makewhatis").

No files are edited by packages. The packages/ports put control information
into /etc/packages and /etc/init.d (for dependencies and scripts respectively).
The sysadmin then runs "makerc" to regenerate the startup Makefile.
If it includes a bunch of small fragments, that seems like an unnecessary
extra complication.

Actually, the Makefile scheme lists dependencies on the single line
that applies to each run-level. Thus (rough example) something like:
level-3: mount-local start-nfs mount-nfs clean-locks clean-tmp ...
mount-local:
mount -t nonfs -a
start-nfs: mountd nfsiod nfsd pcnfsd
...
and so forth. ( The names have been changed to protect the unwritten :-)
