I think it is a good idea to quote one example of "ip route show" where
there is one default route setting and one static route setting. I noticed
that you gave an example to Harald in your mail conversation.
default via 192.168.122.1 dev eth0 proto static metric 1024
192.168.200.0/24 via 192.168.100.222 dev ens10 proto static metric 1
Yes, this is better to help understand the scenario. Will add this in
new patch.
Also, has harald accepted your patch. Has things been sorted out with
him for syntax of rd.route option?
Will sent a new version with change to initramfs because Harald pointed
out my patch has an error on documentation. I guess he just doesn't like
this, not sure about it. Will update if his different diea is clear.
Thanks
