I'm glad you brought that up.  As I was looking through the spec, I was
wondering how deep I wanted to support the configuration.  There are some
"scary areas" in IPMI that I fear configuring b/c so many vendors
implement IPMI poorly.  When a vendor configures usernames/passwords
incorrectly, and bmc-config subsequently messes something up, well, its
only a username and password issue.  in-band IPMI can still work.

Potentially enabling/disabling sensor scanning may make things really bad
on a system.  Sort of like my initial resisitance to add boot-parameter
configuration to bmc-config.

I'm thinking perhaps I will just leave these "scary areas" commented out
in the config after you do a checkout.  That way, if you really know what
you're doing, you are welcome to uncomment and commit away.  It's sort of
like the SOL port field in the bmc-config.  That's a scary config that I
don't want people to write to the BMC by default.

What do you think?
