# also runs standalone (the daemon binds its own socket when not

# No RuntimeDirectory= here: varde.socket creates /run/varde for its

|

# 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.
