--- Comment #9 from Jilles Tjoelker <jilles at FreeBSD.org> ---
(In reply to Devin Teske from comment #6)
It is true that 'set -e' may be a factor with this kind of changes, but there
are two factors which make it almost irrelevant here:

 * The functions in rc.subr are not supported with 'set -e' in effect. This
applies both while sourcing /etc/rc.subr and while calling functions defined in
it.

 * 'set -e' only causes an immediate exit when an untested simple command,
pipeline or subshell returns a non-zero exit status. One of the contexts
considered "tested" is any command before && or ||. Therefore, a compound
command  false && true  will not cause an immediate exit by itself, but only if
its non-zero exit status propagates to an outer function call, pipeline or
subshell which is itself untested.
