 From the looks of it, the boot-archive updation is causing the symptoms 
you mention. The boot-archive is the solaris equivalent of initrd. It 
gets updated when the files in the boot-archive and the "/" filesystem 
get out of sync (see /boot/solaris/filelist.ramdisk).

The command "bootadm update-archive" is run by reboot to do this stuff.
