Re: 24.3. Updating Bootcode

Forgot to send a screenshot
<https://people.freebsd.org/~eduardo/logs/boot%4020220817.JPG> for
loader.efi @ main-n257458-ef8b872301c5
( +Boot0007* FreeBSD-14
HD(1,GPT,73acd1b2-de41-11eb-8156-002b67dfc673,0x28,0x82000)/File(\efi\freebsd\loader.efi)
                         nvd0p1:/efi/freebsd/loader.efi
/boot/efi//efi/freebsd/loader.efi )

Someone talked about this warnings earlier:
---
Attempted extraction of recovery data from stadard superblock: failed
Attempt to find boot zone recovery data: failed
(...)
---
But it boots ok.

Cheers,
