systemd-oomd is desktop-only on Ubuntu (reverse-deps are ubuntu-desktop*);
'systemctl is-enabled systemd-oomd' returns not-found on this server, so
the previous advice to enable it would simply have failed. Recommend
earlyoom instead, with --avoid/--prefer tuned to protect the shell and
target rustc.
Also document the machine-wide alternatives to per-project tuning:
- sudo systemctl set-property user-1000.slice MemoryHigh=/MemoryMax=
(covers every shell and build; sshd lives in system.slice so it can
never lock you out)
- global ~/.cargo/config.toml, which does support [profile.*]
Clarify that the MemoryHigh warning applies to short-lived build scopes,
not to slice-level limits where gradual throttling is appropriate.
