I may have some evidence that, for example,

http://ftp3.freebsd.org/pub/FreeBSD/snapshots/ISO-IMAGES/14.0/FreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20220708-a0b956f5ac5-256605.img.xz

and:

http://ftp3.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/13.1/FreeBSD-13.1-RELEASE-arm-armv6-RPI-B.img.xz

were not built fully via the /usr/src/release procedures
using modern builds of mdconfig and such. The below is
taken from a different list exchange.

I tried what it looks to me the /usr/src/release/
code would do initially for arm64/RPI.conf (but with
my file naming and an explicit -u0 style of use):

# truncate -s3072m mmjnk.test
# mdconfig -u0 -fmmjnk.test -x63 -y255
# gpart create -sMBR md0
md0 created
# gpart show md0
=>     63  6291393  md0  MBR  (3.0G)
      63  6291393       - free -  (3.0G)
# gpart add -t'!12' -a512k -s50m -b1m md0
md0s1 added
# gpart show md0
=>     63  6291393  md0  MBR  (3.0G)
      63     1985       - free -  (993K)
    2048   102400    1  fat32lba  (50M)
  104448  6187008       - free -  (3.0G)

I tried the same sequence in a chroot into a 13.0-RELEASE-p11
tree on an aarch64 main [so: 14] machine. I got the same result.

But such is not what the 13.1-RELEASE build produced, for
example:

# mdconfig -u0 -fFreeBSD-13.1-RELEASE-arm64-aarch64-RPI.img -x63 -y255
# gpart show md0
=>     63  6291393  md0  MBR  (3.0G)
      63     2016       - free -  (1.0M)
    2079   102312    1  fat32lba  [active]  (50M)
  104391  6187041    2  freebsd  (3.0G)
 6291432       24       - free -  (12K)

(There are no 13.1-STABLE snapshots available to download
and look at.)

Looking at the recent 14.0-CURRENT snapshot:

# mdconfig -u0 -fFreeBSD-14.0-CURRENT-arm64-aarch64-RPI-20220708-a0b956f5ac5-256605.img -x63 -y255
# gpart show md0
=>     63  6291393  md0  MBR  (3.0G)
      63     2016       - free -  (1.0M)
    2079   102312    1  fat32lba  [active]  (50M)
  104391  6187041    2  freebsd  (3.0G)
 6291432       24       - free -  (12K)

So, also not matching.
