Well, technically - this is a relatively new process (just a decade
old) introduced with Solaris 10 and OpenSolaris (SXCE and others).

The list of files (including drivers) that must make it to the
boot_archive is here, individually in the current BE:
/boot/solaris/filelist.ramdisk

"bootadm update-archive -R /a" can be run relative to the BE mount
path, likely when you're installing your OS too. If the boot_archive
file is older than any file in this list of its supposed contents,
it is recreated with the up-to-date information.

  It's a filesystem that gets loaded into ram before the / filesystem is 
mounted, and discarded from ram after the / filesystem is mounted.

command line...


I think you can copy your driver and related configuration files
during the installation into your new BE, and modify this text file.
Then update-archive, and the system should be working after boot :)

There is also /boot/solaris/filelist.safe, I'm not sure what it is.
Maybe a leftover from "failsafe boot" which was in SXCE/Solaris 10
and made a similar "initrd" geared towards system recovery if the
boot pool (or SVM mirror) died or got seriously corrupted?..
