But it seems that this has worked for me in the past, when I was creating
these through the GUI. In other words, after the OS installer reboots, it
would correctly reboot in “normal” mode. Am I hallucinating that?
It works in the UI because the HD is the first boot device and the CDROM is
lower in the order. When you boot, it sees the HD doesn't have a boot record
and continues to the next one. Once installed the reboot will have given the
HD a boot record and it will start from there.
Make sure that in your case the CDROM is NOT the first device and I think you
should be alright.
In any case, I’m sure there’s a power-off API method, but I’m not
sure how
to reliably detect when to call it. I could do something hacky like call my
own API endpoint as the last action of the installer somehow (I know how to
with Debian, and I’m sure the RH family can do it as well), but that seems
fragile.
Maybe hack the installer to power power off instead of reboot, and detect
that? I hate the idea of having to fork/maintain my own installer
patches...
What do other people do for automating this situation?
