Created a folder called "--foreign" containing a log file:
Code: [Select]
/usr/sbin/debootstrap: 175: [: =: unexpected operator
/usr/sbin/debootstrap: 415: /usr/sbin/debootstrap: : Permission denied

I even ran it with sudo

Actually, I think you found a bug.
I tried it just now, the following works fine:
Code: [Select]
mkdir root
debootstrap --arch armel --foreign --no-check-gpg squeeze root
qemu-binfmt-conf.sh
cp `which qemu-arm` `which qemu-arm-binfmt` root/usr/bin
chroot root
debootstrap/debootstrap --second-stage

I don't have "qemu-binfmt-conf.sh"
Can you upload a copy?

Edit: or is it this http://svn.kju-app.org/trunk/qemu/qemu/qemu-binfmt-conf.sh

No, that is distro specific. You have to install qemu binfmt support (opensuse: qemu qemu-tools qemu-linux-user debian: qemu binfmt-support qemu-user-static)

So I installed the packages, but I have no idea what to do with them...

Nothing directly. The fact that the qemu-user binaries are registered into binfmt-support will make it possible to finish debootstrap, according to the procedure sketched by Vogtinator, which I had detailed more at some point somewhere :)

Sorry, I tried running "qemu-binfmt-conf.sh", "qemu-binfmt-conf", and just plain "qemu"
Which commands do you mean?
(Sorry if this seems like a lot of questions, but I'm new to this)

I'm up to the .sh file on that, everything else before it has worked.
(Is the .sh file required, I started looking at an article on qemu on the debian wiki. The commands there look similar, but I'm not sure where the .sh file fits in...)

You should be able to run it directly

I can't...
I tried running "update-binfmts --display" and it showed something similar to the .sh file I posted a link to.. should I use that?
Or do you mean just move on to the next set of commands?

http://wiki.debian.org/QemuUserEmulation should help.
It seems you don't have to run it on debian, it will get executed automatically.
You also don't have to copy the files, you have to copy qemu-arm-static only.

I think I understand the general idea of what I'm supposed to do, I just have to figure out how to do it...
As of the last time I tried it "chroot root" gave me the error: "chroot: cannot change root directory to root: Operation not permitted" but I will keep working on it, thanks for your help!

Edit:   :-\ Oops... forgot the sudo... how silly of me. Well, chroot worked.

Edit 2: Debian works, I think... I can't log in... what is the user and password I need to use?

Edit 3: Debian works all the way, now.  :w00t: Forgot you could change the password while using qemu...

I have both the large and small kernels, large and small initrd's, and 2 separate .ll2's for launching them, but both kernels give me the same rootfs error you got in the screenshot in the OP.
