I'm sure it would be doable. However, checkpointing the routes that
way would:
(a) Be inconsistent with how we checkpoint all the other resources,
including the other network resources we handle from the kernel
with rtnl
(b) Require merging of the data from the resources saved in userspace
with those saved in kernelspace
(c) Eliminate the ability for an application to easily checkpoint
itself by making a single syscall
(d) Require this same sort of jumping back and forth between
namespaces by the userspace task doing the checkpoint/restart
