Overview ¶
Package service handles host service installation: launchd on macOS, systemd user units on Linux. Used by `dejima service install/uninstall`.
Package service handles installing dejimad as a host service (launchd on macOS, systemd user units on Linux). The CLI's `dejima service install` command is a thin wrapper over this package.

Functions ¶
func UnitInstalled ¶ added in v0.9.4
func UnitInstalled() bool
UnitInstalled reports whether the dejimad user unit exists on this host.
Distinct from "does this host run systemd", and the distinction is the whole point: a WSL distro can run systemd perfectly well and still have no dejimad unit, because the daemon there is launched from the Windows side. An operator in exactly that state was told to run `sudo systemctl restart dejimad` after a self-update, and the restart the daemon had just attempted had already failed with "is the service installed?".
Types ¶
type Manager ¶
type Manager interface {
// Install registers dejimad with the host service manager. args are the
// extra command-line arguments baked into the service definition (e.g.
// ["--tcp", ":7273"] to expose the Tailscale-pinned TCP listener).
Install(binaryPath string, args []string) error
Uninstall() error
Status() (string, error)
// Restart bounces the running daemon (e.g. after `make install` or a
// release upgrade replaced the binary).
Restart() error
}
Manager is the OS-specific service manager.
type Supervision ¶
type Supervision struct {
Managed bool // a service manager currently has dejimad loaded
Mode string // launchd-system | launchd-gui | launchd-user | systemd-user | none | unknown
RebootDurable bool // comes back after a reboot with no interactive login
Summary string // human one-liner for the report row
Concern string // non-empty → a reboot-survival caveat worth a WARN
}
Supervision describes how (and whether) dejimad is supervised by the host service manager, and whether that arrangement survives a reboot. It answers the question `dejima doctor` couldn't before: not just "is the daemon up?" but "will it come back on its own?".
func Detect ¶
func Detect() Supervision
Detect inspects the host service manager for a dejimad supervision arrangement. Best-effort: never errors; returns Mode "none" when nothing is found and "unknown" on an unsupported OS.
