*DISCLAIMER* I'm no expert myself, but here's what I know.
About RootFS space, main important thing to note is, if you're installing things from the Red side of things (Extras-Testing and Extras-Devel), make sure they're at least a bit optified. Un-optified apps are apps that put most of the files it needs in the limited (but speedy) RootFS space rather then in /opt/.
As such, the best way to free up RootFS space is to KNOW what you are installing. Next, is to uninstall unneeded stuff (especially unoptified stuff).
The cited wiki entry includes moving things around in RootFS to /opt/ and creating symlinks. BE MINDFUL of messing around with files in RootFS, unless you KNOW EXACTLY what they do. Remember, what's safe for other people might or might not be safe for you, *nix is just like that. And some files are in RootFS in the first place for a reason (remember, RootFS is speedy), for instance, the MicroB engine files - MicroB starts faster with the files left in RootFS; or something.
Remember the *nix mantra, "If you have to be told what to do, you have a high potential of messing things up".
But "messing things up" is why most people go to *nix in the first place. That said, have fun optimising your RootFS (or any other part of Maemo for that matter). Just have the flasher app and eMMC/Firmware images close by when you tinker (to reflash when you muck up), and backup as much as you can.
As for me, tinkering step by step, backup-ing all the way. Currently running stock kernel with some theming mods, no hildon-modified and it's funny how things are NOT as hairy as it was before. Phone app is behaving well (used to lock system in portait all the time), and the system is generally very stable with little by the way of slowdowns..
Will try adding Beacon widgets next, see how things pan out.
EDIT: For the guy above, try googling "Sudo Gainroot". And remember, SUDO stands for Super Users Destroy Operating systems.
Lol.
