Perhaps this should be a broader "Immigrant" (or "Refugee"?) community
with sub-communities for the operating systems of origin (Linux, *BSD,
Windows, BeOS, Amiga, etc.).

I personally will find this tremendously useful as an OpenSolaris developer
as I'm often curious about how other operating systems work, but don't
have enough experience with them to feel that I can evaluate them fairly.
Thanks.

You didn't ask for, but here it comes
- a home-made cross reference between AIX and Solaris ;)

I've been doing AIX support for many years.
When I started playing with Solaris at free time, I decided to
maintain a "how to do it in Solaris" reference for myself.

With the intent to share with others later, I made it more like a
cross reference between the two OSs, and plan to add corresponding
resources from Linux and BSD in the future.

Now open the attached HTML file, you will see the content and
the way they're organized are different from Bruce's
http://bhami.com/rosetta.html (which is a remarkable effort).

I group the resources into different system/kernel components.
Each component is a separate HTML table, has links to official
documentation, then resources for separate tasks.
You can see I collected lots of blogs from you guys.

Warning: this is a "Valid HTML 4.01 Strict" file, which means
I.E. doesn't display it correctly ;-)
Please use firefox/mozilla to see the fixed-position menu correctly.

Now that I throw this out, I hope some of you find it useful,
(even though AIX doesn't seem to be popular w/ this crowd ;)
I am going to maintain it, at least for myself. I think
some work need to be done before it reaches broader audience.
Apparently I've been mostly collecting Solaris resources that
I left many AIX parts unfilled.

I don't mind people using the content in anyway, changing
the format, putting it in your own work, whatever.
However I certainly hope it can be a cooperative effort
from now on.
I like the wiki idea, but have no experience with it.
So let me know if you're interested in making it a more
useful resource, how do you want to do it and where
do we put it (I don't have a webserver).

Last but not least, I'd like to see Adam's great proposal
evolves into something useful for all the *nix users/developers,
going all directions, not just a "migration guide from
A to B" or a flame-baiting "comparison between A and B".
If some of you hold a different view, that's fine, in the end
this is an OpenSolaris community :)

Cheers,
Tao
