Wow. Frankly, that article sounds hostile to me. It’s basically claiming to be “Fedora Linux”, then again that it is not but that it is secure as opposed to everyone else; with “curated kernel config and elaborate engineering framework”. A whole $$$$-load of sales pitch.
In the end, you find out that to at least 95%, it is Fedora rawhide distributed as a bootc variant; with a kernel from the same source as the rawhide kernel (minus the Fedora patches); plus some apps built as containers (“hummingbird”) in order to get them from upstream directly rather than packaging them “distroless”, which again is just a sales pitch for “no package manager inside”. What’s the runtime?
So it’s something moving faster than rawhide, with updates “gated” by the basic bootc mechanism (ship working images only, apply atomically).
“The team has already started bringing improvements back to Fedora.” So what is it? Fedora or not Fedora?
There might be even some good ideas in there, but given how this started and how it is communicated I can put zero trust in this.
