21 What have you guys found to be the minimum RAM necessary for a Gentoo
22 system without swap that doesn't lock up? My laptop has 1GB RAM and
23 512MB swap, and when I disabled the swap the system locked up during
24 the first big emerge. I guess that means I need somewhere between 1GB
25 and 1.5GB. I'd say it's a pretty normal laptop/workstation.
