[Nottingham] Gentoo portage tips

Hi Rob,

As someone has already mentioned, do "emerge -U" instead of "emerge -u" to =
upgrade packages. When you do this, it will state ">>> --upgradeonly =
implies --update... adding --update to options.". This is nothing to worry =
about! You should really use "emerge -Uu" I guess, but it doesn't matter.

I believe that adding -D or --deep to the options will do this. You'd best =
look at the man page because I'm not *entirely* sure that it is doing what =
you want.

Cheers,
