Hmm ... here we have something of the order of a hundred systems to
administer (maybe 200, I don't keep count) (quite a few NetBSD, though
various other stuff as well), and depending upon just who you count,
perhaps 5 sysadmins.  The work gets broken down by function - people do
different things, and not all of those 5 know root passwds (almost) anywhere
at all (the almost is to allow for toy systems build mostly for play).

"Get a competent sysadmin" isn't an answer for us, and is actually insulting.
It isn't an answer for lots of other people either - a NetBSD system only
costs a couple of thousand (for a good current system - let alone how cleaply
you can pick up out of date hardware that will function fine) - that much
will only buy a competent sysadmin for a couple of weeks.   For some functions
an organisation might be better off buying an accountant with an adding
machine than a computer if a competent sysadmin were to be a requirement.

There isn't a lot that can be done for the people who really want a single
(old style) /etc/rc (not that there ever really was one, since rc.local
always existed as well).   But for those who prefer to keep rc.conf I
have a suggestion that might work, and be fairly simple for everyone (including
those of us who would prefer not to have to continually fiddle that file).

That is, perhaps the rc.d file could start (for some facility called "frogs")

	frogs=NO		# or YES, depending upon whether NetBSD
				# feels it should be enabled by default

	. /etc/rc.conf		# fetch RC_PATH and other noise

	test -r /etc/options/frogs && {
	    frogs=`sed -n '/^frogs=/s/frogs=\([A-Za-z01]*\).*/\1/p'`
	    frog_flags=`sed -n '/^frog_flags=/s/frog_flags=\([^;]*\)/\1/p'`

and then the rest of the script.  (If sed isn't going to be in /bin, then
for this task, "while read line; do case "$line" ..." type operations will
work almost as well.)

Then, if you really like munging rc.conf, you can simply not have an
/etc/options directory at all, and stick "frogs=YES" and "frog_flags=-squash"
in rc.conf and everything will work.

Alternatively, if you prefer separate files, then you stick lines like


in /etc/options/frogs (perhaps with a bunch of comments about what the
frogs actually do, and what alternatives there are to squashing them) and
that will work as well.

Because the default state of all the various options is in the rc.d file,
nothing (aside from a few settings like rc_configured and RC_PATH) needs to
be in rc.conf or /etc/options to get the NetBSD defined default bahaviour
(put the test lines in a function defined in rc.subr and it even gets to be
trivial to have the default depend upon the settings of other options).
But a grepable comment on the "frogs=YES" line in the rc.d script, and you
can "grep DEFAULT /etc/rc.d/*" to discover the default states of all the
standard included startups.

This way you even get to keep rc.conf if you want, while allowing pkg_install
to create /etc/options/frogs for you if some package thinks it a good idea
to do that (perhaps with =NO set, but some good options in casse you do
want to turn it on).  Then if you prefer to keep rc.conf, you can just
copy the lines from that file into rc.conf (which you would have had to do
under the old system anyway - assuming rc.conf was used at all) and delete
the option file.   Or, if you're like me and prefer separate enable files,
you just change NO to YES in the file, and it is done.
