panic of the day

Here's a quick one. After jumpstarting a box with Solaris 10 update 5 and then applying a recent patch bundle (as part of the JET build) it panics on first boot after the build;

For some reason the boot archive was not being applied to the rootdisk so to fix I just had to boot net -s, mount up the rootdisk to /a and then run "/a/usr/sbin/bootadm update-archive -R /a". This applied the boot archive and then the box could boot. The question as to why the archive wasn't applied is still a mystery that I don't have the inclination to investigate.
