The strategy the Gentoo devs recommend is to run full 64 bit and have a *32-bit* chroot for those apps which don't work when compiled for a 64-bit architecture. Of course, since most everything in Gentoo is compiled on the user's machine and not pre-compiled like Debian, that strategy might not be optimal for Debian. I have three systems, though, only one of which is 64-bit (and none Intel) ;) so if an app doesn't work on a 64-bit box, I just run it on one of the others. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
