I've got a client service (client.service) that requires a server
service (server.service). They are weakly coupled by a polling http
protocol, but the client needs to restart when server does or it can get
into trouble in it's state machine (and can't easily be re-coded to cope).
If I use Requires=server.service in client.service, then the client
correctly restarts when systemctl is used to restart server.service.
However, if the server crashes and is restarted (Restart=always in
server.service), then client is left running.
If I change Requires=server.service to BindTo=server.service in
client.service, then the client is stopped when the server crashes, but
it is not restarted.
Is there some way to get the client to always restart when server
restarts, for whatever reason?
Chris.
