If I build a rootfs image, then change the version (PV) on recipe A, then build the rootfs image again, recipe A rebuilds, then recipe B rebuilds, but it rebuilds without running my custom tasks. There's probably some task flag that I need to set to make this work, but I can't figure out what it is. Any help is appreciated, as always.

We have recently found a cache issue in bitbake with regard to addtask
handling. The fix is now in master:

http://git.yoctoproject.org/cgit.cgi/poky/commit/?id=6db202532122b213ae6cfce9a49ac9fad2db20f5

You can workaround this by removing tmp/cache/ to ensure bitbake
correctly reparses things when it should. It may be the problem you're
seeing, it may not but its worth a try...

Cheers,
