Subject: perf(dracut): replace grep by bash pattern matching
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ddd6a7d3df1c4c5b69d177649279fb82532c2e8a;p=thirdparty%2Fdracut-ng.git

perf(dracut): replace grep by bash pattern matching

Replace `echo | grep` by a bash pattern matching to avoid spawning
external processes. The bash pattern matching should be faster.
