Re: [RFC] Proposal for Adding a Dedicated Debug Kernel Package to Debian(follow-up from DebCamp on DebConf25)
Hi
We talked about this in our last team meeting. We identified some
questions and also some concerns.

Yes, this might be useful for troubleshooting. I don't yet understand
how it would be useful for board bring-up, I would assume this usually
requires code changes.
This would also mean we can overall disable many debug options in the
normal kernel.

Sadly this does not look like it actually includes source. I sincerely
doubt that they modify all those config files by hand this way. But you
can deduct some things.
Mainly they enable
- many DEBUG options,
- many DEBUGFS options,
- some CONFIGFS options, and
- some handpicked things.
Fedora installs the debug kernel as it would any other. But somehow
they manage to reduce the priority.
Problems for Debian current are as follows:
- We have size constraints on our software builders, so right now we
just can't build it.
- We can not make sure it is not used by default.

Bastian
