Erch is Embedded Arch

more proof of concept ATM.

build an chroot via the devtools

sudo mkarchroot -n -C pacman.conf -M makepkg-i686.conf $HOME/erch/rootfs base

After this completes then you need to package it up.

cd rootfs/
sudo tar -zcf ../rootfs.tgz .

Now we create an ext[2,3,4] image

dd if=/dev/zero of=rootfs.ext3 bs=1MB count=0 seek=1024 # seek=1024 = 1GB while seek=2048 = 2GB etc
mkfs.ext3 -F rootfs.ext3
mkdir mnt
sudo mount -o loop rootfs.ext3 mnt
tar -C mnt -zxf rootfs.ext3

This is the root file system of our arch image.

To test I used qemu.

qemu -hda rootfs.ext3 -kernel rootfs/boot/vmlinuz26 -initrd root/boot/kernel26.img append "root=/dev/sda"

It took a while to boot and ran into some errors about a read only file system.
