Hi , I downloaded the latest version of linux-3.11.8 ,configured it as UML and got the statically compiled binary (linux). Then i downloaded the latest busybox 1.21.1 and compiled with default configuration. Then i converted the busybox binary into a ext4 filesystem. while running linux as UML, ./linux ubda=./busybox mem=128M i'm getting the following error EXT4-fs (ubda): mounted filesystem with ordered data mode. Opts: (null) [ 1.170000] VFS: Mounted root (ext4 filesystem) readonly on device 98:0. [ 1.170000] Kernel panic - not syncing: No init found. Try passing init= option to kernel. See Linux Documentation/init.txt for guidance.
