Thanks for your help! I've done so in the past but I've made bad experience. Unfortunately portage isn't so clever, yet. Many times (on the 'clones', as well) I had to block packages before emerge and then unblock again. I even had to unmerge some packages temporarily and emerge them later on again. Sometime I have to patch an ebuild file (temporarily) and so on. And let alone updating baselayout. So, it would be much easier if I could simulate cloning the machines each day.
