I don't know of a distribution that makes any changes to that file after initial installation, but you might as well look through the documentation for your distribution related to md. Also, the worst that would happen is the file gets overwritten, in which case you're back to where you started. Whatever distribution it is, you'll probably also need to rebuild your initramfs/initrd after making the change. --Sarah -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
