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)
1064 984 - 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.
Best,
Fernando
