Me neither, as you can tell:-)

Still, a slapd.conf-option which changes which commands one must run
like that does make me a bit nervous.  Another way might be to give
slapadd a "don't run slapindex" option, and fail if that option is not
specified but the database being updated has linearindex.  Then we can
leave "make slapadd run slapindex at the end if linearindex is given"
on the TODO-list.
