installing arch64 on a new partion from existing arch install?

b9anders · 2009-01-19 11:47:06

I want to make an arch64 install to play with in addition to my current i686 install. I have created an ext4 partition and mounted it as /arch64.

I just want to check that what I am doing is right. Am I correct that the following procedure should install arch64 correctly on my system

1. Modify all links in pacman.conf to point to x86_64 instead of i686.
2. Uncomment the Rootdir line in pacman.conf and have it point to /arch64 instead of /
3. run pacman -Sy base
4. run pacman -S kernel26
5. edit fstab, rc.conf etc to my setup.
6. Add new setup in grub.
7. done.

I am thinking this should give me a base arch install on the new partition. Have I missed anything?

For 2, you can use "-r" to set the root.

Have a look at this wiki page: http://wiki.archlinux.org/index.php/Ins … her_distro

Re 1 - if your pacman.conf is as per the default, you will need to change the links in /etc/pacman.d/mirrorlist, not in pacman.conf itself. When I was doing this the other way around, I created mirrorlist.i686, which was basically my x86_64 mirrorlist and a bit of sed. And rather than change anything in your current system's pacman.conf, I'd suggest creating an alternative pacman.conf.64 and using pacman's --config flag.

thanks guys. Nice pointers on the --config option and the mirrorlist.

Ok, so I went ahead and ran

pacman -Sy base -r /arch64 --config /etc/pacman.conf.64

and I get:
error: scriptlet failed to execute correctly

on a lot of the packages (those who had scripts to run on install I presume). I'm at loss as to what happpened here?

That is probably no good idea; the install-scripts ignore the -r flag and will **** up your current install. This is how I setup a chroot:

CHROOT=/arch64
mkdir -p $CHROOT/var/lib/pacman
pacman --root $CHROOT --sync --refresh
pacman --root $CHROOT --sync --noconfirm coreutils filesystem pacman bash

mount -o bind /dev/ $CHROOT/dev/
mount -t proc none $CHROOT/proc/
mount -t sysfs none $CHROOT/sys/

Now you can `chroot $CHROOT` and continue your installation from there.

scriptlets still fail running this command. Btw, missed this output at the bottom the first time around I ran pacman on this:

sh: /arch64/sbin/ldconfig: cannot execute binary file

I googled a bit and found out that apparently 64-bit binaries can't run on a 32-bit system, although the opposite is the case.

So now, because I am getting stubborn and want this method to work, I am thinking: What if I [temporarily] install a 64-bit kernel in my 32-bit system? I expect stuff to fail here and there, but as long as I can boot in and install the arch64 system via the commandline, I'd be happy.

Terrible idea? Would I need other 64-bit packages just to make the kernel run?

I installed a 64-bit kernel and it ran just as it should. The arch64 install was a success.

well, I have some trouble with hal and hotplugging but that's another issue.

Hi, I'm interested in doing this, but with a twist.

My laptop currently has 32-bit Arch installed, with a separate /home partition and /boot partition. I'd like to install 64-bit Arch on another partition, and I see from this that I can't do it directly using chroot.

However, I currently have 64-bit Arch installed on another computer with proper SSH access and everything. Could I mount my empty partition on my laptop, use sshfs to mount the mount-point on my other computer, and do the setup from there?

Hi, anyone have any idea whether install via SSH is possible?
