1 As best as I can recall, running ikiwiki-mass-rebuild as root has never worked for me on NetBSD or Mac OS X. On both platforms, it gives me a shell as each user in the system wikilist. This is due to non-portable arguments to su(1).
3 The following patch works much better on the aforementioned platforms, as well as CentOS 6:
5 diff --git ikiwiki-mass-rebuild ikiwiki-mass-rebuild
6 index ce4e084e8..2ff33b493 100755

19 The `-m` may be overzealous. I have some sites running as users with `/sbin/nologin` for a shell, and this allows running a command as those users, though without some typical environment variables. This is probably wrong. Maybe I should be doing something else to limit shell access for those users, and the su arg should instead be `-`.
