in xterm as root:

apt-get remove python
apt-get remove python2.5
apt-get remove python-osso
apt-get autoremove
apt-get clean

now you should have much more space.

Thanks for advice, i have went from 45mb to 61.62 free.

hmm i think i already had python optified but i though lets do it once more to see what it cleans up
So it did install many things but the only thing i gained was something from 33 to 36
and after reinstalling some stuff that i need i did fall back to 35 (but maybe a reboot would give me that back)

what does help very well is just disabling the 2 repo's (testing and develop) then it jumps to more then 47

what is exactly stored for that. And cant that be done in home?

Could you tell what this script really does and is it safe?

'Optifying' is not something users do.
...

But in terms of the apps themselves, all the ones in Ovi, and in maemo-extras are optified. They have to have been optified to get that far. Apps still in testing (less so) and devel are (highly) likely not to have been optified. No point in doing that for every build of something that's still in very early experimentation. It's a sort of 'tidying up before public release' process.

Which gives you a fair idea of what you might want to uninstall.

If you still have 20% available (45mb) you should be ok for the Next big Thing.
