I do have a few. I hope you'll make a good use of them to make your
life more productive.

This sounds like you're sure that there is nothing interesting to
see in `emerge --info`. Well, let's change it into something more
correct: according to your knowledge there is nothing interesting to
see. But your knowledge isn't perfect (just like anyone's). Keeping
that in mind while consulting with others is the first of my specific
suggestions into the future. It will save your+our time and may get you
the solution faster.

The second of my specific suggestions into a more fruitful future is:
read what people ask of you. Sending me what I'd asked for would've
taken about a few dozen seconds (I suppose you have the config for
2.6.29 stored somewhere). It certainly wouldn't entail taking your
desktop offline, reemerging udev, etc. etc. It's just attaching two
text files to a piece of e-mail. So if your current attempt at 2.6.36
(was it?) fails, you know what to do right away.

The third suggestion is probably the most important one: being NAT'd
and being behind any iptables configuration (that allows for operations
such as sending mail and browsing the web) doesn't make your PC
invulnerable or anything near that. In other words, active break-in
attempts via open ports is by far not the only option hackers have.

In fact, some people who've appeared on this list over the years would
consider it unacceptably bad netiquette not to include `emerge --info`.
I also recall people who would consider it bad netiquette, but would
still answer your questions (perhaps with some remarks). And I suppose
most others consider it at least a good idea and a potential time-saver
to include it, unless the topic in question is "what laptop should I
buy to run Gentoo". So there goes my last specific suggestion to help
you make a more efficient use of this list: include your `emerge
--info` and relevant config files, if any, in the opening post to a
mailinglist. It's not like you're telling us your card number.
