Kernel menuconfig selects gzip(1) as a default compression format for the
initial ramdisk image.

$ make menuconfig
-> General setup
-> Support initial ramdisk compressed using ...

If instead of gzip(1), you select bzip2(1) or xz(1) format and build a new
kernel, the initramfs image would still be compressed with gzip(1), because
currently there is no way to pass the selected compression format to dracut(8)
via $ make install.

# file /boot/initramfs-3.11.0.img
/boot/initramfs-3.11.0.img: LZMA compressed data, streamed

It shows LZMA because I've patched /sbin/new-kernel-pkg to use

Thank you.
