To anyone thinking this thread is a "solution" to space on rootfs: 1. There's a reason things are where they are, be it for system speed or other considerations. If you do these mods, at the very least you'll be unable to successfully receive OTA updates and will need to manually install, then reconfigure the changes again. Or worse could happen. 2. There's a reason software is still in extras-devel and not moved to at least extras-testing. Not being optified for Maemo 5 is just on of them. Like ossipena said, they may cause other problems like dependency resolution, particularly when updating. Anything from devel should only be used by those willing and able to fix their device when devel stuff breaks it. 3. If you have a space problem on rootfs, the only real solution is to uninstall the stuff using it up or, if you're really good, optify the offending software yourself.
