Subject: ifcfg: Quote left-hand side of [ ] expression
X-Git-Tag: v4.13.0~72
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=1e3197e0fdbf299fe24cdba7c0d613317ed82063;p=thirdparty%2Fiproute2.git

ifcfg: Quote left-hand side of [ ] expression

This prevents word-splitting and therefore leads to more accurate error
message in case 'grep -c' prints something other than a number.
