This is achieved by providing tools and libraries which are similar to use than the equivalents of the most popular existing compression algorithms. LZMA is a general purpose compression algorithm designed by Igor Pavlov as part of 7-Zip. It provides high compression ratio while keeping the decompression speed fast.
rpmlint is silent, package builds against RHEL5 The only thing is that it's not a final version, it's a git snapshot of beta tree.
There is no other option, upstream lingers to release an official version for a long time. The current version is well tested. We have actually rebuilt the whole F12 with XZ payload compression with no problems with (de)compression-ability, which proves it well tested :) XZ is now imported and built.
