I have been wondering why the only binaries for SageMath that are provided officially via the Sage mirrors. Like, I do understand that Debian and Ubuntu are amongst the most popular Linux distributions, but Arch Linux, CentOS, Fedora, Mageia, openSUSE, PCLinuxOS and Gentoo/Sabayon Linux also rank high in popularity amongst Linux distributions (according to DistroWatch, for example).
For Arch Linux there's a fairly up-to-date SageMath package in the official repository (here it is), but with SageMath 6.8 I noticed it lagged about 3 days behind the release of SageMath Linux binaries provided by the official mirrors.
I also wanted to know why Debian and Ubuntu binaries are provided as tarballs and not as the more easily-installed .deb package format.
