Description Ludwig Nussel 2020-06-08 15:46:05 UTC 
Following modification improves boot time by not blocking services that do not actually need network to be up:

/etc/systemd/system/network.service -> /usr/lib/systemd/system/wickedd.service

/etc/systemd/system/network-online.target.wants:
   wicked.service -> /usr/lib/systemd/system/wicked.service

/etc/systemd/system/network.target.wants:
   wickedd.service -> /usr/lib/systemd/system/wickedd.service

/etc/systemd/system/wickedd.service.wants:
   wicked.service -> /usr/lib/systemd/system/wicked.service


That way network.target only brings up wickedd which in turn triggers wicked aka ifup in the background.

as can be seen, wicked continues in the background without preventing multi-user.target getting reached.
