If I understood you correctly, you're trying to get the kernel to execute the "/sbin/init" file of your initramfs. However, "/init" is the sole default initramfs entry point. To fix this, you can pass rdinit=/sbin/init _or_ modify your initramfs image so that "/init" is the entrypoint. Normally, if your initramfs has a /init script your kernel would skip the entire stage where it panics in the perpare_namespace() function for trying to mount "root=" by itself (see init/main.c:init()). -- Dan Aloni XIV LTD, http://www.xivstorage.com da-x (at) monatomic.org, dan (at) xiv.co.il - 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/
