I try not to agree with Perry too often :-), but I do agree with him on all 
of the above.

rc.conf/rc is nice and easy... and probably too limited.

rc.d without run levels gets us 100% of what is needed by at least 95% of 
all sysadmins with only a bit more complication than rc.conf/rc.

rc.d with run levels buys us very little and adds a *lot* of complication 
to typical sysadmins. The folks who need an extra level or two are probably 
quite able to write a script that does the mods they need in rc.d for their 
specific startup action.
