Re: [linux-lvm] lvm with gpt partitioning?

[Josh Duncan <linux-lvm@msmd.net>]

Hi Heinz,

I don't think I can remove the partition, because the EFI firmware needs the
first partition of the disk to be vfat to boot from that disk.  That's not a
concern for this issue right now, but it will be when I want to have my / be an
LVM volume mirrored across sda/sdb.
