Subject: Abort if switch_root does not exist.
X-Git-Tag: 0.1~216
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=7ee170746fe2448e1c4afbafe0c9f0261eb082d9;p=thirdparty%2Fdracut.git

Abort if switch_root does not exist.
Otherwise it would succeed silently when we KNOW it would fail, which is not cool.
Usually this means you didn't build switch_root in your dracut checkout and you used dracut -l.
(This currently cannot be done in a check script, because of the current design of check.
Andreas intends on discussing a redesign on the list.)
