Description (last modified by slelievre)

This is helpful for sage-on-distributions. Typically sage-on-distribution do not want, or need, to call sage's internal packaging system.

I raised this as part of Sage days 77.

If that's all I forgot that's not a bad score. This particular one was different in sage-on-gentoo because I don't ship this database separately from gap like it is done in sage so it doesn't need testing. I'll still need to patch that one one way or another because the path will be different on gentoo. Alternative proposal welcome.

It seems we are working on the same issue ;) #20382 does essentially the same, maybe you want to have a look.

It seems to me that my approach is slightly more generic but I am open for discussion.

Is this still relevant or should it be closed in the light of #20382?

Replying to jdemeyer:

I think I should have marked this one duplicate months ago. There is nothing in here that #20382 doesn't do better.
