# varde system service. Pairs with varde.socket for socket activation;
# also runs standalone (the daemon binds its own socket when not
# activated).

# No RuntimeDirectory= here: varde.socket creates /run/varde for its
# socket file, and the service only uses the activation socket. With
# RuntimeDirectory= on the service, stopping it removed the socket file
# from under the socket unit (0.1.6 and earlier), and preserving it
# (0.1.7/0.1.8) made systemd privatise the directory under DynamicUser -
# /run/varde -> /run/private/varde, 0700 - so no unprivileged client
# could connect at all.
