I used to boot zfs on whole disk(s) from a USB stick with a GPT partition scheme and gptzfsboot on it since FreeBSD version 9 on many testing machines and even production servers without any problems. With the current code base this feature is broken.=20 I found the reason in the source code: In the file /head/stand/libsa/zfs/zf= s.c the feature was disabled in the revisions base r342151 and base r342161.=20 In r342151 disabled to ability to boot zfs from wholes disks. In r342161 is= was refined for the UEFI case.=20 I completely disagree with the reasoning in the commit comment of base r342= 151 and the comment in the source code. As I said in the introduction to this ticket I use and rely on this feature since many years. Furthermore I do not know many systems able to boot zfs from whole disks. FreeBSD is/was one of them. I think we should not give away this precious feature. I propose the following:=20 - Revert base r342151 and base r342161 - Discuss whether the FreeBSD community should give away the feature of booting zfs from whole disks. --=20 You are receiving this mail because: You are the assignee for the bug.=
