Hi,

if I get it correctly [1] it is not recommended to use After=syslog but it's not forbidden. But as the syslog.service should not be enabled it is not running anyway. As the man page states:

"If a unit foo.service contains a setting Before=bar.service and both units are being started, bar.service's start-up is delayed until foo.service is started up. Note that this setting is independent of and orthogonal to the requirement dependencies as configured by Requires=" [2]

it should have no effect including this after even if it's not necessary.

I Would recommend not including the After as it's somehow deprecated since systemd v38 (January 2012!).

The only effect you may observe is that if syslog.service is started through socket activation your service might be delayed starting up resulting in an non-optimal startup time. However, this might take some ms barely anyone would notice that.

best regards Markus

Thanks Simon,I think my question got a bit lost amongst all the grub issues - does anyone else have information about whether any references to syslog.target in systemd unit files can be removed?ChrisSent from Samsung Mobile on O2

Butif a service needs classic syslog, shouldn't it have another After=instead?Simon_______________________________________________Cen tOS mailing listCentOS@centos.org https://lists.centos.org/mailman/listinfo/centos _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
