I don't care if users break their install if they act like a retard during the installation.
In fact, I'm getting pretty tired of this continued discussion about how we can best spoonfeed such people. It is just _impossible_ to make any bootloader the "default" for all use cases.
Imho we should just try to list concisely what the options are, and if package maintainers ask me to discourage use of a specific package, I'll do that. But anything beyond that is optional (and right now, not worth my time)
We could list them something like:
* grub (supports ext*, vfat, reiserfs, xfs. MBR. chainloading)
* syslinux (supports ext*, vfat, btrfs. GPT/MBR. LVM. no chainloading)

If I want to support GPT I will need decent utilities from upstream.
I know about parted and sgdisk but I need a toolset for:
- interactive partitioning
- scripted partitioning (for auto-installs)
- the input format for the scripts should be similar/the same whether you use MBR or GPT.
Basically, if the kernel guys (util-linux) don't care about GPT, I don't think I should either.
I'd rather avoid turning to Gnu (parted) or more obscure (gdisk) upstreams.
Actually I don't get why there is no GPT support yet it util-linux. Am I missing something?

Yeah, archboot is tied to a certain "way of doing things" that's pretty hard to untangle, I think.
Tobias and I have talked about that before, it's definitely not trivial, but it's surely possible.
