Description Andreas Karis 2020-01-23 09:50:44 UTC 
Description of problem:

Hi,

os-net-config will be default create ifcfg-* files for all interfaces that are UP/connected and will instruct them to request an IP with DHCP. This can lead to potential problems on system reboot: if there are lots of interfaces that are connected and requesting an IP through DHCP but their dhcprequest goes unanswered, then we pass the default newtork start timeout of 300 seconds and critical network configuration is not brought up.
