How would you ensure that httpd is actually Apache and not something else?

This one sounds Ok.

I see the same "type" issue as I mentioned, but I see that we use them in
mergetool and web--browse and we haven't heard breakages so perhaps this
is portable enough ;-)

Please avoid ${parameter/pattern/string} expansion, which is not even in
POSIX.  It is bashism and unportable.

Hmm.  If you do discovery like this, maybe you would want to do discovery
for "httpd" the same way?  After all, why look for it only in /usr/sbin?

We've seen this elsewhere and this part should be Ok.
