Example with lingering **disabled**
root> systemd-run --service-type=exec --user --machine eric@.host
/usr/bin/sleep 1m
With this
The systemd --user instance is started for Eric and also the sleep is
started.
However after < 10 seconds or so the transient unit and user service is
all shutdown taking the sleep with it.

I would have hoped the `systemd --user` instance to hang around as long
as systemd-run sleep invocation.
Enabling linger first and then all is good. Would rather not enable linger.
Switching to `--service-type` one shot also works but then the
systemd-run is sync rather than async.
Motivation - Trying to move away from `echo "/usr/bin/sleep 1m" | su -
eric - & `.

Tested on fedora rawhide, systemd-256.5.
