I agree about designing for this user (although I would simply call
them "lightly trained", nothing else).

There currently is no admin interface. You are correct, bash is not

Propose away. Specifications are a great start. I recommend sending
them to this list, and after
some discussion moving them to the wiki.

Replicate ? Right now the image built on disk is suitable for mass
disk replication, with
any server specific configuration done after first boot. Each
machine will need some
initial configuration by the trained deployment teams. After that,
we can expect no one
capable of using an admin interface within a day's travel.
Hopefully, we can remotely
administer servers which have internet connectivity.

You are not "bashing" anyone. You are pointing out where improvement

You are preaching to the choir here. There is no doubt that the
server was sadly neglected
as effort was concentrated on the laptop. For example, I spent
three months last fall fixing
last-minute laptop hardware bugs, instead of working on the server as
and its partners absolutely didn't dedicate enough resources to the
around the laptop. RedHat had more than a handful of engineers (and
continues to have
several) working full time on the laptop software, but none on the
OLPC will be announcing a few hires in this area over the next weeks,
but the real goal
is to get worldwide volunteers pulling in the same direction.
I'll admit I get worried when their suggestion is to change the only
part working relatively well
(the underlying OS, drivers, and networking) instead of working on
the sadly missing parts.

Right now, the basic information (such as functionality and ports) is
You should be able to edit the wiki (you will have to create an
account first, due to spammers)
to create longer lived discussions and add/change information.
The place to go to look for short term contributions is our bug
We try to enter all problems and planned fixes in there to allow
distributed entry, work, and tracking.
Search for school server. Unfortunately, there are many laptop bugs
which mention the school server.
Keywords schoolserver or school server should be added to school
