Re: Parted and UFS/ZFS FreeBSD partition types

In the BSD world, at least, the default partition table type is a BSD disklabel inside an MBR partition. In the past, BSD disklabels without an MBR partition table were at least somewhat common, but they don't seem to be very common today. GPT support in BSD exists, and it's possible to install FreeBSD to a GPT disk, but the last time I checked, the FreeBSD installer couldn't do so directly; you had to do so indirectly in one way or another. (FWIW, the BSDs are transitioning to GPT just like everybody else because BSD disklabels use 32-bit sector pointers, so they're limited to 2 TiB disks just like MBR.)
Just one final question, though
With the "compatibility" MBR partition being created (i.e. the one that appears as 0xEE/GPT in fdisk for say, /dev/sda), is /dev/sda1 and /dev/disk/by-id/ata-BLAHBLAH-part1 then the MBR partition 0xEE or the GPT partition a520?
Linux ignores the protective partition in the MBR on GPT disks, except as part of its verification that a disk is a GPT disk. The device nodes (/dev/sd??, /dev/disk/by-id/*, and so on) all refer to GPT partitions.
If I've suggested a solution to a problem and you're not the original poster, do not try my solution! Problems can seem similar but be different, and a good solution to one problem can make another worse. Post a new thread with your problem details.
