Hi,
I wanted to make a small image out of the proto directory built from
illumos-gate, heavily inspired by pureboot
(https://ptribble.blogspot.com/2015/09/illumos-pureboot.html). I made two (not
working) scripts, the first one boots and give this output while doing so:
Loading unix...
Loading /platform/i86pc/amd64/boot_archive...
Loading /platform/i86pc/amd64/boot_archive.hash...
Booting...
No rootfs module provided, aborting
Hit [Enter] to boot immediately, or any other key command prompt.
Booting [/platform/i86pc/kernel/amd64/unix]
warning: 'environment' is already loaded
warning: 'console-font' is already loaded
No rootfs module provided, aborting
The second script uses bootadm to create the boot_archive, but it doesn't go
past bootadm:
Creating boot_archive for /var/tmp/purebuild.19661
svccfg: Pattern 'system/boot-archive' doesn't match any instances or services

It's not really to serve any purpose, just for fun.
Thanks in advance for any help.
