arch64 upgrade

Leigh · 2007-06-20 04:52:05

I found one other thread about upgrading from archi686 to arch64, but the member decided to reinstall, so nothing was discussed in detail. I should have probably posted in that thread but the disussion kind of went in a different direction. My processor is definately 64bit capable. Anyway since I have my entire system backed up, I thought I would try to upgrade from i686 to 64, vs a complete reinstall. would this be worth the effort? What would happen if I ran the arch64 duke ftp install, only mounting and not formatting, and tried installing over the top of my i686 install? would this be feesable, or would I end up with a huge mess? I don't mind experimenting as I'm very confident I can restore my system back to normal if I have to.

You'd end up with mixed libraries, which I doubt will turn out well.

Not necessarily, you could theoreticly just reinstall every package which would then replace the files with 64bit counterparts. Then again, this method will probably only work from outside with a chroot and even then will cause several issues along the way. That is because some packages run install scripts which depend on other packages already being installed. So one would need to start with a base reinstall and go from there.

I'd try this but that one doesn't go along the idea to walk up the dependency chain from the bottom on.

#!/bin/bash
list=`find /var/lib/pacman/local -type d -not -name local`
pkgs=
for fn in ${list}; do
  pkg=`grep -A1 "\%NAME\%" ${fn}/desc | tail -n1`
  pkgs="${pkgs} ${pkg}"
  unset pkg
done
echo ${pkgs}

WARNING:
I would never recommend to actually do this on a system that's not safe to trash.
Better aproach would be to seperate your data/home partition off of the rootfs and simply reinstall.

Thanks for the script kth5 I did some reading and lots of searching and I'm going to give this a shot this weekend when I have some free time. If it turns out to be as much trouble as i think it will be, I'll just start over with a base install. I have a copy/list of every package I have installed on my system, so at worst getting back to normal from a fresh install won't be too bad.

I'm starting to worry about myself. I don't think it's normal to have memorized my grub menu.list, fstab, rc.conf settings, mkinitcpio settings, and various other conf files!

I don't, I always have to cat /proc/partitions before I mount anything. Usually never change my setups until the machines break. ;p

haha. It just feels odd when realizing I've memorized stuff like that without trying to.

If I end up having to reinstall and I have my /home dir saved. After installing arch64 and installing all the same packages I previously had on i686, will I run into problems by restoring my /home dir.? Reason I ask is because there are many package specific conf files located in /home/liegh

I once had the savegame file for LBreakout2 crash the game when I copied it from PPC to x86. It turned out the file was written in an endian-dependent manner.

I never found anything else to break that way, though.

I ended up just reinstalling from base. It was too confusing trying to upgrade! The install went great. I do miss the Opera web browser, but I read on the opera site that they are working on a linux 64bit version of Opera for their next release. I can't really see much of a speed difference between i686 and 64 except when shutting down and booting which is definately a lot faster.

Lies... arch64 is much faster.

A 64-bit version of Opera is good news as well... options options options.

haha! speed is going to bite us in our arses one day! I can see it now..Like Ack! my computer booted so dang fast it zapped back in time and turned into a pentium1!

Waiting a extra few seconds isn't something I can really notice that much. I'm tempted to add the 32bit stuff so I can run Opera and flash, but I'm going to be patient. I don't want to do a whole bunch of stuff just for a few apps that I could live without. Opera is not one to stay behind. Their developers really kick butt, so I suspect it won't be long.

If you decide to do it, it doesn't take much. Install lib32-qt, and Opera should run. I honestly don't know which lib32 packages are needed for Flash, but it works well here.

I decided to add the chroot arch 32bit enviornment and do it that way. It was hard to live without Opera's email, and it's nice having the 32 bit option when ever I need it.
