# the ntfy-sh module was switching to DynamicUser=true. this test assures that
# the migration does not break existing setups.
#
# this test works doing a migration and asserting ntfy-sh runs properly. first,
# ntfy-sh is configured to use a static user and group. then ntfy-sh is
# started and tested. after that, ntfy-sh is shut down and a systemd drop
# in configuration file is used to upate the service configuration to use
# DynamicUser=true. then the ntfy-sh is started again and tested.
