One big disk space hog is the fact that we don't expire old builds in /var/cache/pbuilder/result/*, there are builds which date back to 2016. There's certain value to keep the last, say six months of builds (e.g. for rollbacks), but anything else does not need to be retained. We could simply add a cron to purge old stuff, that should free ~ 40G or so.
