Easier RAS logging and debuging
+Kernel Parameter Passing Supported
+
+ZeptoOS supports passing arguments to the Linux kernel, a feature
+not available in IBM's kernel. A simple tool allows kernel parameters
+to be set stored and fetched from the ramdisk. This innovation, only

Easier RAS Logging and Debuging
When nodes boot, they send RAS messages to the Service Node.
ZeptoOS has made this easier to use. It is now possible to easily
send debugging and kernel logging messages early in the boot sequence,
-and throughout execution. Tracking down problems is simpler.

Dynamic Status Information with zinfo
+
+
+ZeptoOS includes a tool that maintains dynamic state information on
+BG/L I/O Nodes. The daemon, zinfod
, listens to special
+status information sent during booting and shutdown. This information
+is made available external programs. The user program
+zinfo
provides information on which IO nodes were
+allocated to your job, and can block on their successful boot so
+specific actions can be trigged once the BG/L nodes boot. Similarly,
+a process can wait for an I/O node to shutdown. Dynamic connections
+and interactions with running partitions are now possible.
Customizable Boot Scripts
