The ikiwiki-mass-rebuild utility fails to drop privileges and fails to execute ikiwiki on FreeBSD. The solution is to set the effective UID after setting the real UID, and to set $PATH in the environment before calling exec(). > Why does the PATH need to be reset? --[[Joey]] > > It doesn't - it needs to be set. The line with `%ENV=();` clears the environment, thus no `$PATH` is set. --[[HenrikBrixAndersen]] > > > I guess it shouldn't clear it then.
