+Gentoo: http://en.gentoo-wiki.com/wiki/Initramfs
+
+It is possible to specify multiple initramfs to be extracted during boot. This can be useful if you want to create a generic initramfs (for example one that does mdadm) and then add modifications in separate files (for example a custom /etc/mdadm.conf for every machine). 
+
+http://syslinux.zytor.com/wiki/index.php/SYSLINUX#INITRD_initrd_file
+   It supports multiple filenames separated by commas. This is mostly useful for initramfs, which can be composed of multiple separate cpio or cpio.gz archives. Note: all files except the last one are zero-padded to a 4K page boundary. This should not affect initramfs.
