Do we have any more details on what is broken or how this is happening?
I'm at a loss as to how to help with this.

I added offlineroot_varname at a point when the export D in
rootfs_ipk.bbclass was later. In the final version I moved it and the
other exports earlier to fix different problems. The patch still looked
like a good idea at that point. When a problem appeared with the patch I
decided just to drop it. We should probably continue to export PKG_ROOT
for compatibility and maybe export D in addition to that.

Cheers,
