Subject: Use builtin xz/lzma option to use all cores for multihreaded compression
X-Git-Tag: 035~19
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a76a22b779ba7c0985e60cb853fcf3b4b4147114;p=thirdparty%2Fdracut.git

Use builtin xz/lzma option to use all cores for multihreaded compression

This removes the dependency on 'getconf' as well, which is not installed by default on my embedded systems.
