Curious to know the coolest things you achieved by configuring your kernel. I know kernel config can be boring, but I'm hoping someone will have an impressive answer.
For me I have a very lightweight kernel that runs wayland on nvidia without any issues to date.
Everybody gangsta until they set their block and filesystem drivers to module.
"Oh, did I need to rebuild the initrd too? Shhheeeeit, can I do that in a chroot from a livedisk or something?"
