If this was tested at least once (since I can't test) and @cduston44 does not respond, then I will set this positive review.

Documentation preview for this PR (built with commit 04bdf84; changes) is ready! 🎉

Could this

https://github.com/aclemons/slackware-dockerfiles

be used to test this?

By the way, do we have many sage users on slackware linux distro? Or is @cduston44 the only one as far as known?

It can be tested like our other Linux platforms, using tox -e docker-slackware-current-standard etc.; see tox.ini

(Note that the goal of this PR is not to make everything work. It just makes it testable.)

I forgot that I had made this comment :-)

OK. With this PR, slackware becomes testable in the sense that the test by tox proceeds further than before this PR.

For me, the test fails in building sage even with this PR, anyway.

Perhaps non answerable... I asked because I guess that it is an unpopular linux distro.

I don't know any. When I did the initial porting to slackware, I did it only as an illustration of how to do the porting work for Sage using the Docker technology.

Thanks for the review!
