Am I right? Well, the Linux kernel doesn't really care about partition IDs at all, except in one circumstance - to detect auto RAID partitions. Apart from that, the kernel couldn't care. You could set all your Ext2 partitions as ID 82, your swap as ID 83 and Linux would carry on as if nothing had changed. About the only user programs that know about partition IDs are: - fdisk (its part of the partition table format) - installers (to stop users doing stupid things) -- Russell King (rmk@arm.linux.org.uk) The developer of ARM Linux http://www.arm.linux.org.uk/personal/aboutme.html - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org Please read the FAQ at http://www.tux.org/lkml/
