Yes, indeed. I've got sarge 3.6.8 running nicely.
| |>The next question is what becomes of the |>existing system? | | | That is up to you. You can keep the 64bit system a chroot, if you only | use it occasionally, and mainly stay with 32bits. | Ideally I'd like the 32 bit system to wither away. From what you say below, the only indispensable thing is Openoffice and I could run that from a chroot in a 64 bit system. | If you put the chroot on a separate partition, you can also boot it | directly, and then set up the old 32bit system as a chroot. | | Until all application actually work on 64bit, I would not delete the | 32bit system. I might still come handy at some point. | I agree with that. I have a 200Gb HD but with no partitions (aside from swap) so I have to look into virtual partitions that David was talking about. | |>Specifically, I don't see why the /home directory |>should be effected. | | | Yes, you definately want to share /home, just like /tmp, /proc and | maybe /mnt. If your home is a separate partition, then it straight | forward: just mount it in both places. If not, you have to use the | bind mount given in the HOWTO. Ok, I understand that, then ditto for /opt? | | |>It would be nice if someone with experience installing amd64 over a i386 |>installation could chime in here.

But you also have to | keep at least the libraries from the 32bit system (/lib, /usr/lib, | /usrX11R6/lib and maybe some more places), and tell ld.so about their | new path. If you do that, it is recommended that you keep all of the | 32bit system, so that you can still use its administration tools (like | dpkg). I'm not clear about what the file system would look like if I keep the 32 bit system. I guess when I understand chroot better this will become clear. | | Also several applications still require 32bit libraries. Among these | are openoffice.org, the Flash plugin (which needs 32bit mozilla), | VMware, tcc and of course wine. As I said above OO is essential. I can live w/o flash until a 64bit version is available. VMware, tcc I don't use and I have tried wine and found it more trouble than it's worth. | | Thomas
Thanks Thomas, your posting is really helpful and greatly appreciated. Cheers, Jonathan
