One last thing: is it possible to add support for libdir/prefix to the
deployment process with grub. The problem is that
"/usr/lib/ostree/ostree-grub-generator" path is hardcoded in
src/libostree/ostree-bootloader-grub2.c which works perfectly fine for
normal people, but not that fine if you change 'prefix' during config,
which we do in Yocto/OE.

Thanks,
