Comment 6 for bug 1885164

Might it be possible to automate the new snapcraft offline mode (https://snapcraft.io/docs/snapcraft-offline) for this? I.e. do a `snapcraft pull` to fetch all required data and then build from that for as long as it takes? This would still break builds which require network access in their override-build/stage/prime scriptlets, but I guess that's less likely than a part that builds > 3h on some architectures.

Oh, and please document that time limit somewhere – took me a while to figure out what's wrong when I initially ran into this :-) If it's a good fit on https://snapcraft.io/docs/build-options, I can propose a line through the snapcraft forums.
