Why not mount /dev/sda10 as root and be done with it.? No need to move anything. Do the 64-bit install as you are suggesting. Do NOT install grub. Place the 64-bit kernel in the current /boot pointing at /dev/sda10. Modify grub.conf to allow you to boot either /dev/sda3 (your 32-bit install) or /dev/sda10. (your 64-bit install) Boot both installs a few times and test that each is working. (They will be) Use the 64-bit install for a few days and make sure it's working. When it is don't boot 32-bit for a week or two, just leaving it there on the drive because almost certainly you will have forgotten to copy something over. (I always do...) Only when you are comfortable that 64-bit is working correctly delete the 32-bit on /dev/sda3 if you need the disk space. Remember, leaving /home out of the picture a Gentoo install takes maybe 10GB. It's not that large. Probably less if you shared the portage distfiles directory between the two. It doesn't hurt very much to have multiple installs on the same drive in different partitions. It's what I did playing with a stable and a testing install. I eventually deleted the testing install and just went with stable and a few testing application packages. (I still don't understand why any normal user wants a ~amd64 install but that's just me!) ;-) Hope this helps, Mark
