We still have secure boot disabled by default for Linux systems - it's
something I want to turn on but every time we look at it there are a few
headaches and there's some process in manufacturing too to resolve and
it just never quite makes it high enough in the list to become a priority.

I'm not going to get that solved for this round so I don't think it has
to block this effort. Something I'm happy to look at for platforms later
in the year with F34/F35?

Let me know if I'm missing something important.
