One of the reasons to create partitions is to split up a huge disk so it can be used by different operating systems. In my case, I'd like to set up my Mac-mini so it could boot up MacOS, FreeBSD, or OpenBSD. For that I pretty much need FreeBSD to support APM-style partitions, because the other OS's aren't going to support alternate partitioning schemes. I haven't had the time to try an OpenBSD install yet, but it looks like it takes a single large APM-style partition, and then it knows how to split that up for the separate partitions that it might want. Could we do that with GPT-style partitions, instead of a single APM-stype partition? For PPC on Apple hardware, we already need to have the boot-loader to be sitting on a HFS+ partition (since open-firmware can not read our partition formats). What is the issue with using GPT-style partitions for boot-disks? Is it in finding the boot-loader, or is it the boot-loader itself which has no support for GPT? Would there be less of an issue on PPC since file for the boot-loader itself would not need to be on a GPT-style partition? -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
