Package: dpkg
Version: 1.18.7
lrzip, upstream https://github.com/ckolivas/lrzip has quite good
compression ratio (better than xz at times) with little compromise in
compression time, but at a cost for memory consumption, as seen in
benchmark data provided here:
http://ck.kolivas.org/apps/lrzip/README.benchmarks.
Is there a possibility for dpkg to gain support for lrzip compressed
packages?
