Pools, datasets and snapshots move out of Disks — Disks is the hardware, this is the
filesystem on top of it. New: snapshot schedules, hourly to monthly, with a retention
period and a floor that keeps the newest few whatever their age.
The naming is zfSnap's, deliberately. grid has run zfSnap from root cron since before this
repo existed and it works, so rather than invent a second convention this writes and reads
exactly what zfSnap does: 2026-09-24_02.30.01--6w, with the retention in the name. Ham Lab
can therefore show and expire the snapshots zfSnap already took, the two cannot disagree
about what a snapshot is, and changing a schedule never re-dates old ones — each carries
the rule it was taken under. An existing cron job is detected and shown on the page, with a
warning if a Ham Lab schedule is running as well.
Nothing is destroyed unseen. Every schedule answers what it would delete, with the list,
before Run now touches anything, and only names that parse as a stamp and a TTL are ever
candidates. A snapshot taken by hand is invisible to it.

The app repeated itself. The module list, /api/prefs/dashboard, applyPrefs and the
per-user dashboard blob are gone. Widgets stays and now says plainly that it is for
dashboards outside Ham Lab.
This also closes a bug: applyPrefs set the sampling rate from intervalMs inside the
dashboard layout, and reset it to the default when that field was absent — so with
per-user layouts, one account saving a dashboard could reset the sampling rate for the
whole machine. The sampler now has one source.

The login is a user name and a password. The old single password becomes the account
named after the OS user on first boot, along with its sessions and the machine-wide look.
Settings gains Users (add, remove, reset a password — your own password confirms) and
Sessions (device, IP, last seen; revoke one or sign out everywhere else). Theme, accents
and the dashboard layout follow the account; the refresh rate, graph history and alerts
stay the machine's. Pairing a machine takes a user on it. Log lines name the actor.

The process table's columns fit the box they are in, the rate control saves, curves are
timed on the viewer's clock and keep to the stride, the power icon is drawn, and a young
history draws in from the right instead of being stretched.

Each machine keeps 300 points per curve whatever the window, so memory doesn't follow it;
a wider window means wider points, each the average of its bucket rather than one instant
out of it. The hub passes the setting to every machine it manages.

Alerts: rules over sensors, watched fleet-wide from the hub; ntfy and webhook channels;
firing count on the rail. Docker: containers by stack with live use, start/stop/restart,
following logs, inspect, images/volumes/networks. Skins: HUD, Nord, Gruvbox, Catppuccin

- hamlab install / uninstall (internal/setup): systemd or OpenRC, elevates through
sudo or doas, runs as the invoking user, sets or generates the password, names only
journal groups that exist, waits for /healthz, reports an active firewalld/ufw.
--purge and the data chown never touch a directory that isn't Ham Lab's alone.
- install.sh: curl-able bootstrap (arch detection, SHA256SUMS, offline beside the
binaries, noexec /tmp fallback). make release builds dist/ for amd64, arm64, arm
(ARMv6), 386, riscv64. Every build is CGO_ENABLED=0; the native one used to link glibc.
- internal/priv replaces every literal `sudo -n`: uid 0, sudo or doas.
- Updates acts on dnf, zypper, pacman and apk as well as apt; dnf shows installed versions.
- Services falls back to the plain systemctl table before systemd 246 and says so on
hosts without systemd. Disks falls back to /sys/block without lsblk.
- Listener binds with IP_FREEBIND, so a LAN address that isn't up at boot is no failure.
- Self-update: the new build must pass `check` against the live config, is put in
place by atomic rename, and the daemon re-execs itself (same under any supervisor).
- State and config writes are fsynced; a corrupt state.json is set aside, not fatal.
- Terminal shutdown no longer empties the saved list, so names come back after a
restart by design rather than by winning a race.
- Config default is ~/.config/hamlab; an existing ~/apps/hamlab is still found.
