delonix system boot

Persistência no arranque: units systemd para os containers voltarem a subir no boot.

Boot persistence: systemd units so containers come back up after a reboot.

boot enable gera uma unit systemd por container em execução (rootless → user units + loginctl enable-linger; root → system units), com ExecStart =container start. Assim os containers voltam a subir quando o host arranca, sem daemon.

boot enable generates one systemd unit per running container (rootless → user units + loginctl enable-linger; root → system units), with ExecStart=container start. So containers come back up when the host boots, with no daemon.

`boot enable`

Install + enable systemd units so containers come back after a reboot.

Covers the ones running now AND the ones whose own policy says they should be (always/unless-stopped) — a reboot kills the supervisor, so those are stopped precisely when it matters. Stale units whose container is gone are removed. Rootless uses user units + linger.

Usage: delonix system boot enable [OPTIONS]

Options:
      --l18n <en|pt>
          Output language: `en` (default) or `pt` (Portuguese, pt_AO). Also settable via `$DELONIX_L18N`. Global — works before any subcommand

      --restart <RESTART>
          Restart policy baked into the units (`no|on-failure[:max]|always|unless-stopped`).
          
          Omitted, each unit inherits the container's own policy (`always` if it has none). Given, it applies to every unit — including `no`.

  -h, --help
          Print help (see a summary with '-h')

EXAMPLES:
  # one unit per RUNNING container; rootless installs user units and turns
  # linger on, so they start without a login
  delonix system boot enable

  # bake a gentler policy into the units than the `always` default
  delonix system boot enable --restart on-failure:3

DesafioChallenge

Em rootless, confirma que a unit gerada é uma user unit (não system) e que loginctl enable-linger ficou activo para a tua conta — sem isso a unit nunca arrancaria antes do login.

In rootless mode, confirm the generated unit is a user unit (not a system one) and that loginctl enable-linger got enabled for your account — without it, the unit would never start before login.
