I installed bash-static on all our FreeBSD hosts.  I would love to
solely rely on what the base system provides but sadly I have never
encountered a case with any OS where that is true.  And rewriting my
admin scripts to sh from bash is a task that I simply do not have time
for at the moment.

Enumerating bash-static along with postfix, sudo, tmux, tree, vim,
etc., that we require for FreeBSD is quite natural and poses no
particular difficulty.
