Specify rootfstype=ramfs to get the old initramfs behavior. The previous initramfs code provided a fairly crappy root filesystem: didn't let you --bind mount directories out of it, reported zero size/usage so it didn't show up in "df" and couldn't run things like rpm that query available space before proceeding, would fill up all available memory and panic the system if you wrote too much to it... Using tmpfs instead provides a much better root filesystem. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
