Hello Mark, Wednesday, October 31, 2018, 12:38:07 AM, you wrote: >> After that loader, loaded from p2, loads kernel from p3 and boots >> system from p3! > Are the kernel's on p2 and p3 distinct in an identifiable way? > Can you be sure it was not a mix of the p2 kernel and p3 world > that booted? I ask because . . . Maybe, it is kernel from p2 and userland from p3, but anyway, it is not what I want to achieve. I'll add other kernel IDENT for other partition for check, but I'm sure, that p3 is moutned as /. I have different /etc/fstab on different partitions, of course. If kernel on "bootme" GPT partition will be faulty, it will be disaster, as gptboot could not (or I can not find how to) switch "bootme" attribute of GPT partition. I want to migrate my NanoBSD images from MBR to GPT, but I can not find way to easily boot from "previous" partition when "new" one is messed up. > Any chance that that /etc/fstab initially used points > to p3's world for / ? /etc/fstab on p2 points to p2, and /etc/fstab on p3 points to p3, I'm sure. -- Best regards, Lev mailto:lev@FreeBSD.org
