Hi Hiren,
I think the check for socket's domain should be enough?

Upgrading boot from GPT(BIOS) to GPT(UEFI)
Hi everyone, A few months ago I got myself a new box and I have been happily running FreeBSD on it ever since. I noticed that the boot was not as fast as I had expected and I've realized that, while my disk is GPT partitioned, the boot process is still BIOS based: % gpart show => 34 976773101 ada0 GPT (466G) 34 6- free - (3.0K) 40 1024 1 freebsd-boot (512K) 1064984- free - (492K) 2048 67108864 2 freebsd-swap (32G) 67110912 909662208 3 freebsd-zfs (434G) 976773120 15- free - (7.5K) I am reading uefi(8) and it looks like FreeBSD 11 should be able to boot using UEFI straight into ZFS, so I am thinking of converting that freebsd-boot partition to an EFI partition, creating a FAT filesystem and copying /boot/boot.efi there. How good of an idea is that? Would it really be that simple or am I missing something? My only reason for wanting to boot with UEFI is faster boot, everything is working fine otherwise. Thanks in advance for your help.

I would recommend creating another partition for EFI instead of replacing your freebsd-boot partition, in order to have a working fallback in case EFI boot doesn't work. You would need to steal some space from your swap partition. Otherwise, it's a good idea, and it really is that simple. I did exactly that when I updated a machine to 11 and switched to EFI. $ gpart show ada0 => 34 500118125 ada0 GPT (238G) 34 6- free - (3.0K) 40 1024 1 freebsd-boot (512K) 1064 1600 2 efi (800K) 2664 10485144 4 freebsd-swap (5.0G) 10487808 489629696 3 freebsd-zfs (233G) 500117504655- free - (328K) $ sysctl machdep.bootmethod machdep.bootmethod: UEFI Eric ___ freebsd-stable@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"

I am also interesting by this case. I think expand freebsd-boot to about 1M (size of /boot/boot1.efifat), dding /boot/boot1.efifat and set to type to 'efi' may be enough.

No need to touch > swap partition. Yes, this is almost exactly what I have done on a machine that was originally installed with gptzfsboot on the first partition, which was 512K. Since all the partitions on this SSD were aligned to 1M, I reduced the size of the first partition to 224K, freeing up a hole of exactly 800K for an EFI partition: => 40 976773088 ada0 GPT (466G) 40 2008- free - (1.0M) 2048448 1 freebsd-boot (224K) 2496 1600 4 efi (800K) 4096 33554432 2 freebsd-swap (16G) 33558528 943214592 3 freebsd-zfs (450G) 976773120 8- free - (4.0K) Then I wrote the preformatted boot1.efifat image to it, using: gpart bootcode -p /boot/boot1.efifat -i 4 ada0. You can also use dd of course, but I prefer using gpart for these kinds of manipulations. This way, you can choose between booting in old school BIOS mode, or UEFI mode. If the UEFI mode works flawlessly, you can always decide later to dump the freebsd-boot partition, and use only an EFI partition. -Dimitry P.S.: The only thing that triggers my OCD here is that the EFI partition has index 4, but is physically the second. But I can live with that, until I finally delete the freebsd-boot partition. :) signature.asc Description: Message signed with OpenPGP using GPGMail
bsdconfig
Hi All I wouldn't mind a little info on bsdconfig. I couldn't so far seem to find what I was looking for. I have a FreeBSD 11.0 server up and running fine. I added an additional drive and wanted to format and initialize the drive. I thought bsdconfig could do this but strangely, I can't seem to. It treats what I want to do as part of a fresh install and keeps saying I need to install a root partition.
