Ok, the route table item must be a line like "192.168.100.1 via 127.0.0.1 dev
lo metric 203"
If passing them via cmdline we need quote it with some special character and
append
it to the ip= cmdline param
The other way is copy the route file to /etc/ in initramfs like you are doing.
But we did need the functions to handle the static route.
So leave to Harald about the interface.
