/tmp is a RAM-backed tmpfs on Ubuntu (50% of RAM). Agent runs fill it: half the RAM goes, then every temp-file creation fails with ENOSPC and shells break. Swap does not lift the cap, so the fix is /tmp on disk. End-of-install offers (Linux, [y/N], skipped without a terminal, idempotent): - offer_tmp_on_disk: mask tmp.mount + etc/tmpfiles.d/tmp.conf (wipe at boot, 10-day purge, /var/tmp rule kept). Effective at next reboot. - offer_ssh_memory_guard: the previous server's rules. ssh.service drop-in (OOMScoreAdjust=-1000, MemoryMin=256M) + earlyoom with --avoid sshd and --prefer node/java. MemoryMin covers sshd only; earlyoom is the real guard. install_cloudpex deploys the NAS mount helper in the Linux block. Docs: README steps 12-14 + table, CLAUDE.md layout + lint command.
