I'm not sure how many other Linux distributions use something else
besides Bash for sh. NetBSD uses ash for '/bin/sh', and last I knew,
so does FreeBSD.

I agree wholeheartedly. Conversely, I've seen scripts that implicitly
invoke Bash but make no use of Bash's extensions. Unfortunately,
unintended(?) Bash-isms tend to make using another shell from Bash as sh
potentially problematic on Linux systems.

Care would have to be taken with scripts that source others as is the
case with some of Slackware's initscripts.
