Thanks, but it must be something different - or I was not clear describing the problem. On system B, where there is no network restriction, I have always cleared distfiles/ contents after each update without problem. Portage downloads only the packages needed for the most recent update, not also the ones already used for the previous updates. I'm sure it keeps a database of the installed packages somewhere, it does not rely only on distfile/ contents. raffaele
