- * Changelog
- * ~~~~~~~~~
- *
- * Thu, 22 Aug 2002 15:10:43 +0200
- *      - Update Config.help entry. I got a number of emails asking
- *        me to tell their senders if they could make use of this
- *        piece of code... So: "SRM is something like BIOS for your
- *        Alpha"
- *      - Update code formatting a bit to better conform CodingStyle
- *        rules.
- *      - So this is v0.0.5, with no changes (except formatting)
- *      
- * Wed, 22 May 2002 00:11:21 +0200
- *      - Fix typo on comment (SRC -> SRM)
- *      - Call this "Version 0.0.4"
- *
- * Tue,  9 Apr 2002 18:44:40 +0200
- *      - Implement access by variable name and additionally
- *        by number. This is done by creating two subdirectories
- *        where one holds all names (like the old directory
- *        did) and the other holding 256 files named like "0",
- *        "1" and so on.
- *      - Call this "Version 0.0.3"
- *

+          kexec is a system call that implements the ability to shutdown your

+          but it is indepedent of the system firmware.   And like a reboot
+          you can start any kernel with it, not just Linux.
+
+          The name comes from the similiarity to the exec system call.

+          support.  As of this writing the exact hardware interface is
+          strongly in flux, so no good recommendation can be made.
