Well, if nothing else, you could use binfmt support in kernel to execute 64bit code on 32bit OS, as same as you can execute ARM or other arch binaries. On the other hand, booting 64bit live system would be much easier, faster and better approach, I guess :)
If you don't want to mess with chroot from Fedora, you can use Gentoo amd64 Live DVD, which can be downloaded from http://gentoo.osuosl.org//releases/amd64/11.0/ Best regards, Peter 2011/11/1 Sebastian Beßler <sebast...@darkmetatron.de> > Am 01.11.2011 20:51, schrieb Dale: > > > Don't boot a 32 bit OS and chroot into a 64 bit one.
