Comment:
With kernel 4.19.192_1, I get: `open /usr/lib/modules/4.19.192_1/modules.builtin.modinfo: no such file or directory`

It built fine for 5.11.22_1 though.

I think we should document a umask policy; the final image is world-readable, so you should call `umask 0077` in the kernel install script first (see `initramfs-regenerate` hook!)
