Starting network services from emergency mode command prompt ?

Monday, 29 October 2018

Hi all.

I accidentally interrupted a dnf update and messed up the boot process on
my server.   I got the machine booting to an emergency mode command prompt
via grub2 commands. (Painful !)

I need to run dnf with a network connection to finish fixing things.  I
tried grub2-mkconfig, but it needs more than that.

How does one get networking running in Fedora 28 x86_64 from the emergency
mode command prompt ?

Thanks
