Editing Ubuntu without templates

This tutorial will teach how to install the newest Ubuntu versions through chroot (no templates required).

==Initial steps==

* Choose a number for your machine (example: 101)
* Choose an ubuntu version (this howto was tested with hardy, intrepid and jaunty)
* Go to the directory where the images will be placed:
 cd /vz/private/
* Create a directory for the new machine:
 mkdir 101
* Run debootstrap:
 debootstrap --arch=i386 jaunty 101/ http://br.archive.ubuntu.com/ubuntu
(you can change the mirror if you want)
* Edit the machine configuration in /etc/vz/conf/101.conf. Configure its name, IP, memory and everything else
* Start the machine
 vzctl start 101

==Fixing bugs==

===udev===
If you try to enter the machine you'll see an error:

 eva:/vz/private# vzctl enter 101
 enter into VE 101 failed
 Unable to open pty: No such file or directory

To solve this, you'll have to remove udev from the boot:

 eva:/vz/private# vzctl exec 101 'update-rc.d -f udev remove'
 Removing any system startup links for /etc/init.d/udev ...
 /etc/rcS.d/S10udev

Then you'll be able to enter the machine after restarting it:

 vzctl restart 101
 vzctl enter 101

Note: when you update the udev package you'll probably have to run the "update-rc.d -f udev remove" command again.

===klogd===

Type this command:
 ps aux

You'll see that "init" didn't finish because the "klogd" process is still being run. You'll have to fix this:

 update-rc.d -f klogd remove

Restart the machine and see the results:
 exit
 vzctl restart 101
 vzctl enter 101
 ps aux

===network===

For newer ubuntu versions, you'll notice that the network is not working. To fix this problem, you'll have to edit the /etc/init.d/networking script. You'll have to make it create the "/var/run/network" directory just after its "start":

  case "$1" in
    start)
      mkdir -p /var/run/network # -> this is the new line
      process_options

Then, start the networking:

  /etc/init.d/networking start

(important: use start, not restart)

===getty===

If you look at the running processes, you'll see that there are a lot of "/sbin/getty" processes. You can also remove these.

===Other init stuff===

Feel free to use 'update-rc.d' to remove any other unneded stuff =)

==Finish==

Now you're free to use your machine =)

You'll still probably want to add the "security" and "updates" repositories, install openssh-server, change the root password, update the system, change locales and other stuff. Enjoy =)
