Subject: Default to xz fast compression
X-Git-Tag: v15~188^2~9
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c2dcf199b81d5da6cd5ea27bdb44b2e0402ec74e;p=thirdparty%2Fmkosi.git

Default to xz fast compression

Let's default to fast compression instead of better compression.

Also drop pixz support since it's superseded by xz's own multithreading
support.
