  not sure if you're suggesting i should now be able to build for,
say, beagleboard with the meta-ti layer, but i cloned meta-ti into my
yocto tree, added that layer to bblayers.conf, and tried to

$ bitbake core-image-minimal

and got what i believe gary was referring to above:

$ bitbake core-image-minimal
Pseudo is not present but is required, building this first before the main build
ERROR: ParseError at /home/rpjday/yocto/git/meta-ti/recipes-misc/payload/bonescript.bb:5:
Could not inherit file classes/systemd.bbclass
ERROR: Command execution failed: Exited with 1

  or am i misreading what you wrote?
