Just a note here: Theoretically, it's possible to return from
". foo", so it should be possible to accomplish this with
if ! [ -z "${_rc_subr_loaded}" ]; then return; fi
_rc_subr_loaded="YES"
(or variants thereof), but for some reason this never works
during booting. (It works fine when I run a standalone shell
script.)
If anyone can work out how to do this properly, please go
ahead and fix it. :-)
