Currently, if /etc/openssl/certs.conf doesn't exist, `certctl rehash'
(the crux of `postinstall fix opensslcerts') will print an error
message and then exit with status 0.  This combination is a bug --
need to think a bit about it, but probably better to exit nonzero than
to suppress the error message.

So if you unpack new _non-etc_ sets, `postinstall fix' won't
clobber your /etc/openssl/certs directory.

The etc.tgz set, however, will have /etc/openssl/certs.conf.  So if
you naively unpack etc.tgz, `postinstall fix' will clobber your
/etc/openssl/certs directory.

That said, I think if you use etcupdate(8), it will interactively
prompt you before creating the new /etc/openssl/certs.conf.  (Have
made a note to add this in my etcmerge(8) tool to do a three-way merge
for updating (x)etc sets too.)

I'm open to other suggestions about how to handle the transition from
manually maintained /etc/openssl/certs on (say) 9.x with no certs.conf
or certctl(8) to 10.0 with new default certs.conf and certctl(8),
provided that

(a) new installations get /etc/openssl/certs populated out of the box,


(b) on _future_ updates (like 10.0 to 10.1, where both releases have
    certctl(8) and a default certs.conf), /etc/openssl/certs gets
    updated too (unless you set `manual' in /etc/openssl/certs.conf).
