Help text

It's compression ratio and speed is intermediate. Decompression speed is slowest among the choices. The initramfs size is about 10% smaller with bzip2, in comparison to gzip. Bzip2 uses a large amount of memory. For modern kernels you will need at least 8MB RAM or more for booting.

If you choose this, keep in mind that you need to have the bzip2 tool available to be able to compress the initram.
