 I think a special environment *is* needed. Perhaps the trap info
 when your system crashed would be informative?

 I execute almost exactly this commandline routinely on three
 3.0-current boxes, with and without the detach. Only the
 filenames are different. Two of them are even run from /etc/ttys
 where the -detach parameter is mandatory to stop init spawning
 bunches of them and then complaining about it being run too
 frequently.
