Subject: fix(dracut-install): do not fail when SOURCE is optional and missing
X-Git-Tag: 057~60
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=bd1a5ca9ae9e347061e67e51be29335ab074ad95;p=thirdparty%2Fdracut.git

fix(dracut-install): do not fail when SOURCE is optional and missing

When running dracut-install with '-o' (optional source), and nullglob
at the same time, when all of the arguments evaluate <null>, dracut-install
should not fail even when the source is not specified.
