apt-get tells me that to dist-upgrade to the new linux-image-2.6.26-2 (lenny5.0.1) an additional of more then 70MB disk space will be used.Why is that? Doesn't the previous linux image be replaced by the new one,maintaining approximately the same disk space? Or can I get rid of the old one after a computer restart(and the remove of the old one is not done automatically)?
