I'm not aware of any persistent storage for this in any Linux distribution.

I've always just created a shell script with the commands and arranged 
for it to be run on start up.

There may be something if you look at Bird / Quagga / Zebra / etc that 
supports multiple routing tables through their config.

Hi.
Nope, there isn't a native way to store this info in filesystem to
restore at the boot. All implementations of similar feature are
distributive-specific.
If you use the interfaces file for network configuraton, then the best
way is use of post-up statements in interface configuration section.
Check 'man interfaces' for details.

I'm using Ubuntu and am assuming they need to be added to /etc/network/interfaces or elsewhere (/etc/rc.local) to be applied on startup unless someone knows otherwise.
