TODO: I'm still hanging onto code that extracts hostname and
timezone from profiles until which time I'm sure that its removal
won't interfere with testing.
Curious. Does this code being left in include the current support
for the embedded SC profile? I'm noticing that's still in
there and it's something that should be removed by this project.
Indeed, the embedded SC profile code should be removed from the AI
client, since the AI client code is bound to the AI service image.
In a light of CR7023449 Anna recently filed, how process
of fetching SC manifest will work in case AI is booted from media ?
With William's project, the management of configuration profiles is
decoupled from the AI manifest, which will indeed be a big change for
users because the configuration profile has always been inside the AI
manifest since the early versions of AI; however, this is the model
we're moving toward.
Yep. I understand this and support that model.
I was just wondering how that is going to affect the scenario above.
As a result of this change, the AI booted from media use case will
change a little bit as well. Namely, the AI manifest provided at the
prompt will no longer contain a configuration profile in its content.
This use case has always been a bridge to the true usage of AI over
the network and in that comparison, it can be looked at as a
semi-interactive mode. As such, the plan for this use case is to have
SCI tool get launched upon first boot after an AI installation where
no configuration profile was provided. This will be true for the AI
netboot case as well, so in that sense, it will be consistent. I'm
not certain yet how we will configure for SCI tool to get launched,
but your thoughts on this is appreciated.
I see. Thank you for clarifying that. It sounds reasonable.
I think early on we discussed that it would be nice if SCI tool (or
the service that launches it) could just automatically detect if one
or more of the "basic" configuration parameters were missing. Is this
still the case?
It is not part of current design, only explicit way is to be supported.
When originally thinking about implicit approach,
all possibilities seemed too fragile and limiting the end user. In
particular, I think we can't reliably guess user's intent
based on what parameters were configured in SC profile. Also, booting
the system with completely skipping configuration
step should be possible.
Based on that, system/config smf service will invoke SCI tool only if
appropriate smf property is configured. It could be
done by dropping canned profile on target - it would just configure SCI
tool related smf property.
If not, we could perhaps make the AI installer just guestimate that
when no profiles are given, it should set whatever property it needs
to set on the system-config service to launch SCI tool.
Yep. I think we could deliver pre-canned SC profile (for instance as
/usr/share/auto_install/sc_profiles/sci.xml)
which would be used by AI client in case of bootable AI.
I am not sure how network AI should behave in case that no SC profiles
are supplied from AI server -
in that scenario, do we also want to 'force' invoking SCI tool at the
first boot or would it be
better to let user make that decision (i.e. assign that SC profile on AI
server if interactive post-install
configuration is desired) ?
Thank you,
Jan
