Bug#892323: busybox: Broken DHCP setup with multiple gateways
Package: busybox
Version: 1:1.22.0-19+b3
Severity: normal
Dear Maintainer,
* What led up to the situation?
Trying a installation in our local network.
* What exactly did you do (or not do) that was effective (or
ineffective)?
DHCP is configured to server *two* IPv4 gateways.
* What was the outcome of this action?
Debian-Installer fails to setup IPv4 networking.
Claims that "no routers" were configured.
* What outcome did you expect instead?
A working network configuration.
See attached patch.

Subject: [PATCH] Allow multiple routers
Organization: Univention GmbH, Bremen, Germany
According to <https://udhcp.busybox.net/README.udhcpc> "$router" is "A
*list* of routers", so do not quote it to allow IFS splitting.
Running the following command by hand shows the error:
udhcpc -i ens3 -V d-i -T 1 -t 59 -O router -f
...
ip: an inet address is expected rather than "192.168.10.13 192.168.10.14"
