After sending my initial posting I thought I should have mentioned the details of that laptop, as there are older and newer, slower and faster ones ... I think mine is somehow middleclass these days (correct me ...): Acer TM 634 P4-M 1.8GHz (cpu family : 15, model : 2) 512 MB RAM 30 GB 5200 rpm HDD So it is not *that* constrained in terms of RAM and disk, I assume. But I am also ready to go the -Os-way if you recommend/suggest it for my system. Thanks a lot, Stefan. -- gentoo-user@gentoo.org mailing list
