Changes

Run debootstrap to install a minimal Ubunty Gutsy system into that directory:

Some packages does not make sense in a VE. Remove those:

[VE]# rm -fr /lib/udev

On a usual Linux system, getty is running on a virtual terminals, which a VE does not have.

First way:

[VE]# rm /etc/event.d/tty*

Second way:

[VE]# dpkg -P system-services

Second way can be dangerous for future versions of system-services, but it's OK for now since the only service they carry is running gettys.

[VE]# chmod 700 /root

[VE]# usermod -L root

[VE]# apt-get update && apt-get upgrade

<small>This didn't show anything for me, but might do something in the future.</small>

[VE]# apt-get install ssh quota

Feel free to add packages which you want to have in a default template to this command.

This is only useful if you installed SSH above. Each individual [[VE]] should have its own pair of SSH host keys. The code below will wipe out the existing SSH keys and instruct the newly-created [[VE]] to create new SSH keys on first boot.

Turn off doing <tt>sync()</tt> on every write for <code>syslog</code>'s log files, to improve overall I/O performance.

<pre>[VE]# sed -i -e 's@\([[:space:]]\)\(/var/log/\)@\1-\2@' /etc/syslog.conf</pre>

Link <code>/etc/mtab</code> to <code>/proc/mounts</code>, so <code>df</code> and friends will work:

[VE]# rm -f /etc/mtab

[VE]# update-rc.d -f mtab.sh remove

[VE]# sed -ie '/tmpfs/d' /etc/init.d/mountkernfs.sh

In most of the cases you don't want klogd to run -- the only exception is if you configure iptables to log some events -- so you can disable it:

[VE]# update-rc.d -f klogd remove

After installing packages, you'll have some junk packages laying around in your cache. Since you don't want your template to have those, this command will wipe them out.

[VE]# apt-get clean

[VE]# echo "localhost" > /etc/hostname

[VE]# echo "127.0.0.1 localhost.localdomain localhost" > /etc/hosts

Now everything is done. Exit from the template and go back to the hardware node.

[VE]# exit
