Using the likes of:

=
http://ftp3.freebsd.org/pub/FreeBSD/releases/ISO-IMAGES/13.2/FreeBSD-13.2-=
RC3-arm64-aarch64-RPI.img.xz

directly seems to produce installations with a constant:

kenv -q smbios.system.uuid
30303031-3030-3030-3265-373238346338

that ends up being what is used for /etc/hostid .

It looks like this traces back to the U-Boot
involvement in the boot sequence:

# kenv | grep smbios
hint.smbios.0.mem=3D"0x39c2b000"
smbios.bios.reldate=3D"10/01/2022"
smbios.bios.revision=3D"22.10"
smbios.bios.vendor=3D"U-Boot"
smbios.bios.version=3D"2022.10"
smbios.chassis.maker=3D"Unknown"
smbios.chassis.type=3D"Desktop"
smbios.planar.maker=3D"Unknown"
smbios.planar.product=3D"Unknown Product"
smbios.socket.enabled=3D"1"
smbios.system.maker=3D"Unknown"
smbios.system.product=3D"Unknown Product"
smbios.system.serial=3D"REDACTED"
smbios.system.uuid=3D"30303031-3030-3030-3265-373238346338"
smbios.version=3D"3.0"
