As per Issue #5 the Kernel will grow quite in size, so it's vital to be able to make it smaller, since the growth of the rootfs.cpio.xz isn't that much of a problem.

@landley pointed out his microconfigs which are sadly neglected by upstream.

Furthermore bloatcheck seems to be a good choice to dive into and reducing loglevel as much as possible may also improve the situation.

As the boot issues have been fixed early printk() can be removed.

As of now, the most space-saving technique is to use xz for compressing both bzImage and initramfs.cpio.xz and yeeting all the other compressions at the Kernel Configuration.

As of now, basically everything has been gutted that isn't necessary to boot besides:

  • PC Speaker Support
  • ISA Support
    • PC/104 Support
  • /sys support
  • /proc support
  • /dev support
  • TTY support
  • Network Drivers
    • 3Com
    • AMD
    • Intel
    • VIA

It doesn't even have Filesystems Support built in!
