Network is not ready when executing run_cmd commands

[brandhout]

Version (k3OS / kernel)
k3os version v0.22.2-k3s2r0 5.4.0-88-generic

Architecture
x86

Describe the bug
Network is not ready when executing run_cmd commands, I can only run route commands or iptables commands in combination with a sleep.

To Reproduce
Install a fresh k3os machine on kvm or bare metal

run_cmd:

• "route add default gw 192.168.1.254 eth1"

Or some other route command or iptables

Expected behavior
The route command is added to the system routing table

Actual behavior
route: ioctl 0x890b failed: network unreachable
sleep 5 && route add default gw 192.168.1.254 eth1 works

Additional context
I've got two network interfaces, one connected to the internet (eth1) and one internal network without access to the internet.
