Subject: run-parts: add --exit-on-error | -e support
X-Git-Tag: 1_22_0~271
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=0496e824a5b97edc9991f62c7c74f9b24b16edc7;p=oweals%2Fbusybox.git

run-parts: add --exit-on-error | -e support

The "big" run-parts supports a handy --exit-on-error to stop execution on
errors, so lets support it as well.

Upstream doesn't have a short option for it, but I've used '-e' for busybox.
