A /0 subnet mask is theoretically valid, but ip route get doesn't allow
it:
$ ip route get 1.0.0.0/0
need at least a destination address
Remove the check so that it can go through:
$ ip/ip route get 1.0.0.0/0
1.0.0.0 via 192.168.1.1 dev eth0 src 192.168.1.91 uid 1000

Stephen et al, this was reported by a Debian user:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=921737
It makes sense to me at a cursory glance, but sending as RFC as I'm
not 100% familiar with the route get function.
