OK, then nothing to worry about there. I have no idea which shell
OpenBSD and NetBSD use these days, and I don't have access to a box.
Anybody?
OpenBSD uses pdksh in Bourne shell mode for non-root shells (ksh mode
for root) [1].
NetBSD >=4 uses a Bourne shell but I don't know the exact provenance.
[2] "A sh command appeared in Version 1 AT&T UNIX. It was, however,
unmaintainable so we wrote this one."
