[yocto] Smart/RPM automatic feed configuration

[Alex J Lennon]

I'm using RPM package feeds with smart, and am wondering how to
configure up the feed sources easily at build time?

I see in 3.4.5 of the reference manual it talks about base-feeds.conf
for opkg but I'm wondering if there's a variable
I can set in local.conf to correct setup, say, the URL prefix for the
needed feed sources for the image?

Thanks,

Alex
