The original ash (at the time of 4.3BSD-Net2) was such a replacement
of the SVR4 Bourne shell.  But with the next "traditional" BSD release,
4.4BSD alpha, the shell was already aiming at POSIX; and so were the
shells on NetBSD (1.0 ff) and FreeBSD, soon.

However, there is a relation from 4.3BSD-Net2, 386BSD, earlyNetBSD to
a Linux port, and thus a Bourne-like ash interestingly survived with
Slackware until 2007 (8.1).

dash in contrast was an independent, later port from NetBSD to Linux
and was a modern variant from the start.
