waitid is supported on FreeBSD. Regarding prctl(2), it seems upstart is supposed to handle Linux kernels w/o prctl(PR_SET_CHILD_SUBREAPER) support gracefully by printing a warning and just ignoring respawn statements, so the same could be applied to non-Linux kernels. Of course there's other things that might need porting currently. Regards, Guillem -- To UNSUBSCRIBE, email to debian-devel-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
