The attached change to /lib/svc/method/update-man-index should (I think) only update the directories (if any) that are not current, so that most of the time, it finishes in a second or so rather than a couple of minutes (less clutter in svcs -xv shortly after system comes up).

Hi,

This looks like a really useful change and it will be nice to see the
processes not hanging around after reboot. This script comes up from upstream
illumos-gate so that's where the change would be made in order for OpenIndiana
to pick it up.

You do need a / after the first 'find' argument so that symlinks like
/usr/man are followed and I would probably just check whether there is
any output from find rather than invoking wc and tr. Something like:

    [ -d "$p" -a -f "$p/whatis" ] && \
        [ -z "`find "$p/" -type f -newer "$p/whatis"`" ] && \
        continue  # save time, do not re-index manpath element if current

For illumos-gate, lines need to be < 80 characters too.
