Use a service unit, not a scope unit, to restart
Reportedly `systemd-run --scope` still got killed by the service
manager; see #4615. The suspected cause is that `scope` units are run by
the `systemd-run` process itself and inherit the caller's execution
environment (see systemd-run(1)). To fix this, we use a systemd
`service` unit instead, which is run and managed by PID 1 - hopefully
this will isolate us sufficiently so that we don't get terminated along
with `jellyfin.service`.

# restart.sh - Jellyfin server restart script
# Part of the Jellyfin project (https://github.com/jellyfin)
#
# This script restarts the Jellyfin daemon on Linux when using
# the Restart button on the admin dashboard. It supports the
# systemctl, service, and traditional /etc/init.d (sysv) restart
# methods, chosen automatically by which one is found first (in
# that order).
#
# This script is used by the Debian/Ubuntu/Fedora/CentOS packages.
# This is the Right Way(tm) to check if we are booted with
# systemd, according to sd_booted(3)
if [ -d /run/systemd/system ]; then

else
# Everything else is really hard to figure out, so we just use
# service(8) if it's available - that works with most init
# systems/distributions I know of, including FreeBSD
if type service >/dev/null 2>&1; then
cmd=service
else
# If even service(8) isn't available, we just try /etc/init.d
# and hope for the best
