pkgbase on armv7 (rpi2b v1.1) questions

Hi,

On systems like these, a bootable image is provided for convenience
with default logins. I'm guessing these images aren't pkgbasified.

[] is pkgbase expected to work on armv7? if so, are there instructions
    somewhere showing how?

[] if yes, can one follow -current-nodebug with pkgbase?

I'm not at all keen to pkgbase all the things, but think it'd be 
ideally suited to very low powered machines
