[sage-devel] Packaging Sage?

Hello, TL;TR: Packagers, how do you deal with Sage to package it for your Linux distribution (or *BSD system)? Details: Sage has been ported to FreeBSD many years ago (4.8), but now the port is lagging and no more packages are built; I'm trying to fix it. Problem: on FreeBSD, packages are built

Are you sure you don't have a problem with the size of the ram ? You certainly have spool virtual memory partition. I have run some programs on a PI (3) (not Sage), and when the memory was full, I have got some segmentation faults (this should not happen, but..). This was on raspbian, two years ag
