Created page with "===Devuan Jessie=== Start this process on a existing Devuan system. You will need to have the Devuan patched version of debootstrap installed. Create a empty image file and..."

New page

===Devuan Jessie===

Start this process on a existing Devuan system. You will need to have the Devuan patched version of debootstrap installed.

Create a empty image file and format it with ext3.

dd if=/dev/zero of=devuan_jessie.img bs=1M count=1 seek=1024
mkfs.ext3 devuan_jessie.img

Create a directory to mount the image on. Using '/mnt/img' for this example.

mkdir /mnt/img
mount -oloop devuan_jessie.img /mnt/img

Start the debootstrap process.

debootstrap --variant=minbase jessie /mnt/img http://auto.mirror.devuan.org/merged/

Once that completes, copy your existing /etc/apt/sources.list to the new image so we can run updates.

cp /etc/apt/sources.list /mnt/img/etc/apt/

Here is a basic sources.list

deb http://auto.mirror.devuan.org/merged jessie main
deb http://auto.mirror.devuan.org/merged jessie-updates main
deb http://auto.mirror.devuan.org/merged jessie-security main

Mount the necessary system files so that we can enter the new root filesystem with chroot.

mount --bind /dev /mnt/img/dev
mount --bind /dev/pts /mnt/img/dev/pts
mount -t proc proc /mnt/img/proc
mount -t sysfs sys /mnt/img/sys
chroot /mnt/img

Run updates and install a language pack.

apt-get update
apt-get upgrade

Configure the system timezone.

dpkg-reconfigure tzdata

Install the kernel image, SSH server and the full version of vim

apt-get install linux-image-`dpkg --print-architecture`
apt-get install openssh-server
apt-get install vim

To use the Xen console 'xm console (domU)' you need to setup a tty on /dev/hvc0. Edit /etc/inittab and add this line.

co:2345:respawn:/sbin/getty 38400 hvc0

The default udev rules for Devuan ignore Xen generated MAC addresses so you won't get a '/etc/udev/rules.d/70-persistent-net.rules' This causes your network interfaces not to come up.

Edit '/lib/udev/rules.d/75-persistent-net-generator.rules' and comment these lines. Here's the changes in patch/diff format.

<syntaxhighlight lang="bash">

</syntaxhighlight>

====Final Cleanup====

Set a hostname.

Remove /etc/udev/rules.d/70-persistent-net.rules so that network comes up clean when the image is booted for the first time.

Remove SSH host keys so that new ones get generated on first boot.

Set a root password

<syntaxhighlight lang="bash">
echo 'trusy' > /etc/hostname
rm /etc/udev/rules.d/70-persistent-net.rules
rm /etc/ssh/ssh_host_*
passwd root
