systemd experimental

mise can declare Linux systemd user services in [bootstrap.linux.systemd.units] and apply them with mise bootstrap systemd apply:

[bootstrap.linux.systemd.units.my-sync]
description = "sync files"
exec_start = "~/.local/bin/my-sync --watch"
after = ["network-online.target"]
wants = ["network-online.target"]
environment = { PATH = "/usr/local/bin:/usr/bin:/bin" }
working_directory = "~"
restart = "on-failure"
restart_sec = "5s"
standard_output = "append:%h/.local/state/my-sync.log"
standard_error = "journal"

Each unit is written to ~/.config/systemd/user/dev.mise.<name>.service and managed with systemctl --user. Unit names may contain letters, numbers, ., _, -, and @. mise owns only the service files it creates with the dev.mise. prefix.

Supported keys

TOML key	systemd key
description	Description
after	After
wants	Wants
exec_start	ExecStart
environment	Environment
working_directory	WorkingDirectory
restart	Restart
restart_sec	RestartSec
standard_output	StandardOutput
standard_error	StandardError
wanted_by	WantedBy
start	run systemctl --user restart

exec_start and working_directory expand bare ~ and ~/ to the current user's home directory before writing the service file. wanted_by defaults to ["default.target"]; set wanted_by = [] to write the unit and disable any previous enablement. start defaults to true; set start = false to write and enable without keeping the unit running.

Semantics

• Declarative and additive — unit names merge across the config hierarchy (global → project). A more local config replaces the full declaration for the same unit name.
• Linux-only — on other platforms the section is inert: mise bootstrap systemd status lists entries as skipped and mise bootstrap systemd apply ignores them.
• User services only — mise writes to ~/.config/systemd/user and uses systemctl --user. System services in /etc/systemd/system are not supported.
• Target user only — run mise as the user that owns the services, with an active systemd user bus. sudo mise is skipped because systemctl --user would target the wrong user manager.
• Manual application only — mise never writes or starts systemd services implicitly; only mise bootstrap systemd apply and mise bootstrap do.

Commands

mise bootstrap systemd status            # shows systemd user service state
mise bootstrap systemd status --json     # machine-readable
mise bootstrap systemd status --missing  # exit 1 if any unit is missing, changed, or inactive

mise bootstrap systemd apply           # write and start missing/changed units
mise bootstrap systemd apply --dry-run # print the commands without running them
mise bootstrap systemd apply --yes     # skip the confirmation prompt

status reports each unit as active, inactive, differs, or missing. apply rewrites changed service files, runs systemctl --user daemon-reload, enables units with wanted_by, disables units with wanted_by = [], and restarts them when start = true or stops them when start = false.
