One thing that we don't yet store that wtmp does is the kernel version at boot. We should probably make the ck-log-system-start tool store the uname release in the log file. The ck-history --last report should show this as well. Maybe if we have support in reboot for booting into another system we should support logging that as well... see also http://lists.freedesktop.org/archives/consolekit/2009-September/000044.html
