This is because with commit https://github.com/systemd/systemd/commit/7d85383edbab73274dc81cc888d884bb01070bc2 they have changed them to be 10% of the physical memory instead of the default of 50%. This is a potentially breaking, or at least an unexpected behaviour change, especially for people using tmpfs on /tmp for compiling. Maybe we should make a news item to let people know that they either need to add an fstab entry with size option set, or better, create a systemd local override with relevant content. Cheers, Zoltan
