From acc5f0d94b05378a6f68667742775f84dfdc7fe2 Mon Sep 17 00:00:00 2001 From: Darren Hart Date: Tue, 19 Mar 2013 15:15:06 -0700 Subject: mkefidisk: Use msdos partition tables While GPT works fine when writing to actual media, it cannot be reliably used for distributing disk images as it requires the backup table to be on the last block on the device, which of course varies from device to device. Use MSDOS tables instead. Use mkfs to label the filesystems as msdos tables do not support partition labeling.
