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 $INITRD_COMPRESS variable.
