seatd-launch starts a seatd instance with a dedicated socket path, waits for it to be ready, and starts the specified command with SEATD_SOCK set appropriately. Once the specified command terminates, the seatd instance is also terminated.

seatd requires root privileges to perform its tasks. This can be achieved through SUID of seatd-launch or by running seatd-launch as root. seatd-launch will drop privileges from the effective user to the real user before running the specified command. If the real user is root, this is simply a noop. You should only run seatd-launch as root if you intend for the specified command to run as root as well.

seatd-launch serves a similar purpose to the libseat "builtin" backend, but is superior to it for two reasons:

1.The specified command never runs as root
2.The standard seatd executable and libseat backend is used

seatd-launch exits with the status of its child. When the child terminates on a signal N, seatd-launch exits with the status 128 + N.

If seatd-launch fails because of another error, it exits with a non-zero status.
