I did a test rebuild (fresh install), which went through without issue. Now that machine has 4GiB of RAM (Hetzner CAX11) and a swap file of the same size, so it’s certainly less constraint than the 2+2 GB setup mentioned above. However, swap use was minimal during the whole build and the maximum RAM usage I saw was ~3.1GB. And most of the time, it stayed around ~2GB, so it doesn’t look too bad (build time was more or less unchanged, i.e. about 8 minutes).
