Subject: fix(base): remove grep dependency
X-Git-Tag: 058~53
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=240a1d34bd5d98fb8a7d75cd1053d8abf1c73f64;p=thirdparty%2Fdracut.git

fix(base): remove grep dependency

The base module requires grep with the `rd.memdebug=1` command line parameter.
As this code is broken if grep is not added by other means and grep is only
required for this, rewriting this code to avoid the dependency.
