They should appear automatically as soon as tracker has had a chance to finish its job. It could not do it until now because of no space in rootfs. If nothing happens in an hour then restart tracker manually but you should not need to. You've removed most of it already by running 'rm -rf /and'. Then there is the installer and the kernel. I don't know enough about Nitroid to give you an authoritative answer. I would just go with post #43 but post #47 says it's not that simple. You can definitely remove the installer by Code: sudo gainroot apt-get purge nitroid-installer and leave the kernel be, or follow the link in post #47 to find out more. Hopefully not but that depends on what else have you done to it that we don't know.
sudo gainroot apt-get purge nitroid-installer
