Can minimyth filesystem be in a partition on USB drive?

Post by Grant_Edwards » Thu Mar 12, 2009 3:43 pm

I'm still weighing different boot configurations for my Mac
Mini setup. In order to boot from a USB flash drive, it needs
to be partitioned using a GPT partition table. If I add GPT
partition table support to the MiniMyth kernel, will the
startup scripts find the "minimyth" filesystem if it's in a
FAT32 partition on the flash drive instead of being in the
"root" device? e.g. /dev/sdb2 instead of /dev/sdb?

As long as the partition has the label 'minimyth', I do not know of any reason why it would not work.

Cool.

That means that if I add GPT partition table support to the
linux kernel, I should be able to create a stand-alone, bootable,
MiniMyth-on-USB-flash-drive for Mac.

I think. Mac firmware is a bit obtuse.

Right now, you have to install grub+kernel+rootfs on the
hard-drive. Now that I think about it, putting grub on the
hard-drive and kernel+rootfs on the USB drive _might_ work.

Still, it would be cleaner if you didn't have to touch the
hard-drive at all.

I may also try included the Intel framebuffer driver just to
see if I can get the graphical startup to work (personally, I'm
just as happy with messages scrolling by), but I'm curious...
