Anybody else clear on the Kernel Documentation?
Above just isn’t that clear to me.
I have read snippets from github and the mailing lists of a more abstract overview of custom kernels, but it seemed conflicting, and the docs and github just refer you to mailing list users who’ve tried to hack custom kernels, instead of providing proper documentation references.
I don’t want to go off-topic, maybe this isn’t UX related as such, but given the lack of documentation and differing advice across different qubes channels, I’m no longer clear.
1) Are there security implications to custom kernels? (i.e. is there a super duper modification in dom0 that can only work with fedora kernel and I would have to manually migrate this to my custom kernel?)
2) (really what I’m lacking, which would answer the question) - What is Qubes actually doing to the kernel? What modifications are being made? What does it need to function (respective parts - xen, qubes packages/interfaces)?
Really 2), answers 1). I’ve read that some custom modifications are made to dom0 kernel which make it difficult to change dom0 distro (but apparently new&upcoming qubes APIs make this less of an issue?). I understand the abstracts of kernels, and I understand the abstracts of Qubes. What I do not understand is what Qubes needs in a Kernel (in dom0, and in a VM), for xen, interVM comms - to work with various qubes packages, etc.
If I understood this, I could then go an build a custom kernel. Idk about anyone else, but I find forraging for custom kernel building docs easier than understanding what Qubes needs kernel wise, and what the implications are.
