# 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)

    # 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
