The service is now user-bound: each user runs their own daemon with
their own config ($XDG_CONFIG_HOME/yams/config.toml), corpus
($XDG_DATA_HOME/yams) and socket ($XDG_RUNTIME_DIR/yams-daemon.sock),
which is exactly what the CLI already resolves. The system service, its
yams account/group, the group socket and the /etc/yams/config.toml
configuration go away.
- Unit: /usr/lib/systemd/user/yams-daemon.service runs
`yams-daemon --foreground` with default path resolution,
Restart=on-failure, WantedBy=default.target, and light hardening
(NoNewPrivileges, LockPersonality, RestrictRealtime, RestrictSUIDSGID,
native syscalls only). No ProtectHome/PrivateTmp: the daemon reads the
files its user adds.
- Enablement: /usr/lib/systemd/user-preset/80-yams.preset plus
`systemctl --global preset` on first install (and on upgrade from a
release with the system unit), so the unit starts with every user's
next session; administrators override with a user preset or
`systemctl --global disable`, and later upgrades keep that choice.
Package scripts never start per-user instances: they reload running
user managers, try-restart running user daemons on upgrade and stop
them on removal (`systemctl --user` via runuser per /run/user/<uid>),
then `systemctl --global disable` on removal.
- Migration from 0.20.x and the system-service design: deb preinst, rpm
%pre and Arch pre_upgrade stop and disable the old system unit while
its file is still installed (deb also purges deb-systemd-helper
state). /var/lib/yams, the old system corpus that the CLI never
reached, is left alone and documented; user corpora are never
touched.
- The sysusers entry, account creation and the deb's passwd and
init-system-helpers dependencies are dropped; the deb purge no longer
deletes /var/lib/yams.
- Install paths move to lib/systemd/user and lib/systemd/user-preset in
meson, the Arch stage/PKGBUILD and the install-surface policy.
- docs/install.md: the user service, enabling it now
(`systemctl --user enable --now`), lingering, plugins via the user's
config, opting out, upgrade and removal behaviour, and the 0.20.3
leftover.
