I never heard of pixz. Is it still actively developed? I see that the last release is already four years old and in Debian we have the same version since oldstable. I just don't want to add code to support unmaintained or rarely used software. It also seems that since pixz actually *changes* the data it is supposed to compress in case it receives a tarball, it came up with a new file ending *.tpxz. Currently, mmdebstrap supports all compression file endings supported by tar and tar currently does not know about pixz. Is there a reason why tar maintainers thought they don't add that compressor to their list? Thanks! cheers, josch
