## NOTE: there's two different bootloader setups here:
## ppc/chrp: for normal PPC systems. needs 'addnote' run on yaboot.
## uses /etc/yaboot.conf, as is the default.
## ppc/mac: for PowerMacs. no 'addnote' (it breaks some Macs!)
## ofboot.b picks one of /ppc/ppc{32,64}/yaboot.conf for yaboot,
## thus automatically booting the correct kernel for the machine.

Add ability for external templates to graft content into boot.iso I originally added --add-template to support doing something similar to pungi, which injects content into the system to be used by default. However, this causes the content to be part of the squashfs, which means PXE installations have to download significantly more data that they may not need (if they actually want to pull the tree data from the network, which is not an unusual case). What I actually need is to be able to modify *both* the runtime image and the arch-specific content. For the runtime, I need to change /usr/share/anaconda/interactive-defaults.ks to point to the new content. (Although, potentially we could patch Anaconda itself to auto-detect an ostree repository configured in disk image, similar to what it does for yum repositories) For the arch-specfic image, I want to drop my content into the ISO root. So this patch adds --add-arch-template and --add-arch-template-var in order to do the latter, while preserving the --add-template to affect the runtime image. Further, the templates will automatically graft in a directory named "iso-graft/" from the working directory (if it exists). (I suggest that external templates create a subdirectory named "content" to avoid clashes with any future lorax work) Thus, this will be used by the Atomic Host lorax templates to inject content/repo, but could be used by e.g. pungi to add content/rpms as well. I tried to avoid code deduplication by creating a new template for the product.img bits and this, but that broke because the parent boot.iso code needs access to the `${imggraft}` variable. I think a real fix here would involve turning the product.img, content/, *and* boot.iso into a new template.
