+ * This is stage1 init for ROCK Linux advanced rescue system (C) 2004 Tobias Hintze
+ *
+ * Plan:
+ *  - mount boot filesystem
+ *  - mount tmpfs as new root filesystem
+ *  - extract system.tar.bz2 and overlay.tar.bz2 from boot filesystem into new root filesystem
+ *  - move /dev under new root
+ *  - do pivot_root into tmpfs
+ *  - exec /sbin/init in new root
+ * 
+ * This init accepts the following (kernel append) parameters:
+ * *_PARAM macros hold parameter names only!
+ * 
+ * SYSTEM_FAILURE_PARAM - action to be taken if extracting system fails
+ *  (panic|reboot|shell)
+ * 
+ * OVERLAY_FAILURE_PARAM - action to be taken if extracting overlay fails
+ *  (panic|reboot|shell|ignore)
+ * 
+ * SYSTEM_LOCATION_PARAM - name and path of system.tar.bz2
+ *  NB: boot filesystem mounted as /mnt_boot
+ * 
+ * OVERLAY_LOCATION_PARAM - name and path of overlay.tar.bz2
+ *  NB: boot filesystem mounted as /mnt_boot
+ * 
+ * BOOT_DEVICE_PARAM - device that holds boot filesystem
+ *
+ * STAGE2_INIT_PARAM - executable to be run in stage2
+ *
