Configuring IPv6 Address in a Hook with dhcpcd

[ReeseWang]

I'm currently working on getting dhcpcd to add routes to a routing table that isn't main. It appears that the only method to accomplish this is by utilizing the --noconfigure command line option, and then setting up the interfaces and routes within hooks.

While implementing this, I logged all the environment variables in my enter hook but couldn't find any variable that holds the IPv6 address provided by the DHCPv6 server. Can someone guide me on how to assign the IPv6 address to my interface in this scenario?

Additionally, is there a dhcpcd.conf configuration setting that serves the same purpose as the --noconfigure command line option?

@ReeseWang why don't you want the routes in main? Maybe it's easier to allow dhcpcd to fit your use case?

Here's an example of DHCP6 addresses exported:

reason=REBIND6
interface=vioif0
protocol=dhcp6
