Description Francesco Turco 2018-08-10 16:34:02 UTC
Currently source tarballs for sys-apps/portage are released using the .tar.bz2 format, which is not as space efficient as .tar.xz.

On my system:

> $ du -k portage-2.3.45.tar.{bz2,xz}
> 988     portage-2.3.45.tar.bz2
> 904     portage-2.3.45.tar.xz

(portage-2.3.45.tar.xz has been compressed by me without any special tar setting besides --xz)

So we can effortlessly save about 8.5% of disk space and bandwidth.

What do you think?

Reproducible: Always

Yes, .tar.xz would be fine, since it's supported by EAPI 5 that we use in the ebuilds.
