Ok, got it.

The only correlation there is a link to a web page containing PGP-signed
checksum files (for the ISOs).
This is "new" as of 10.2-RELEASE. So, what I mean (or meant to say) is
poudriere could fetch the base.txz file, fetch the signed checksum (of
the MANIFEST), and compare it against something like this:
https://www.freebsd.org/releases/10.2R/CHECKSUM.SHA256-FreeBSD-10.2-RELEASE-amd64.asc
Hopefully that makes it a bit more clear on what I meant.
