tar has support for lzip, but only works if the lzip program is installed. unfortunately it isn't in the Arch repos.
this also affects the "mtools" package which contains 'lz' and 'uz' that both need lzip binary.


Steps to reproduce:

$ tar xvf moe-1.6.tar.lz
tar (child): lzip: Cannot exec: No such file or directory
tar (child): Error is not recoverable: exiting now
tar: Child returned status 2
tar: Error is not recoverable: exiting now
$ pkgfile /usr/bin/lzip
This task depends upon

Reason for closing:  Won't implement
Additional comments about closing:  lzip is not a dep of tar. Find someone to add this package in official repositories.

Who uses this? Does bsdtar work (it has native support for lzma).

the first and only thing I've ever seen that does use this strange format, but yes, thank-you - bsdtar extracted it fine.
(I tried and failed with 7z, xz, and lz4. "lz" from mtools package just calls lzip...!)

maybe then (as nobody uses lzip) this could be re-assigned to mtools (as a bug) because 2 of the programs that provides just crash without lzip

lzip option cannot be disabled. './configure --without-lzip' set the lzip path to 'no'.

lz and uz are shell wrappers which may call gzip, bzip2 and lzip based on file extension. Not really different than tar.
