init emulation and pid conflict just don't make sense in grub.
--help/--version can make sense, so return would be fine.

It does not make sense in grub either, it's along the usual double-fork
used by brltty to detach from the starting shell.

No.

Ideally it should, but in practice if the system has so low memory for
the extremely little use of brltty, it is unusable already anyway.
