Provides the systemd template zerotier-online@.target asserting that a particular ZeroTier network has come online.
The instance name of the template can be either a ZeroTier network id or network name, for example:
-
zerotier-online@b3ccb0264b417d78.target -
zerotier-online@cool-network.target
My laptop mounts some CIFS shares on boot, connecting to the file server over ZeroTier.
The mount units must wait for the ZeroTier network to come online before they are started, otherwise they will fail to start during boot and must be manually restarted once logged in.
Setting a dependency on network-online.target is not enough: network-online.target is reached as soon as the wireless network comes online, but the wireless network being online is itself a prerequisite for ZeroTier connecting. It is not desirable to make network-online.target wait for the ZeroTier network to come online as this would unnecessarily delay other units from starting, so we need to split the ZeroTier network dependency out into its own target unit.
And so we've arrived at the purpose of this package. Setting a dependency on the zerotier-online@.target target will wait for the ZeroTier daemon to start and connect to the network we need.
Here's an example mount unit that waits for the ZeroTier network named cool-network to come online before attempting to mount the //fileserver/data share:
