If you already have a GNU/Linux system, lxc would be the easiest to setup.

= Install required packages =

Install lxc using this command.
{{{
sudo apt-get install lxc
}}} 

If you have Ubuntu 14.04/trusty then install lxc from backports
{{{
sudo apt-get -t trusty-backports install lxc
}}}

{{{#!wiki important
Arch/Manjaro users see https://wiki.archlinux.org/index.php/Linux_Containers
}}}

Now install some necessary packages for networking support for the container.

{{{
sudo apt-get install -qy libvirt-clients libvirt-daemon-system iptables ebtables dnsmasq-base # if libvirt-client is not available, try libvirt-bin
}}}

= Networking setup =

Check status of libvirt daemon (service)
{{{
systemctl status libvirtd }}} 

and start if not running
{{{
systemctl start libvirtd }}}
 

Now start the networking service using
{{{
sudo virsh net-start default
sudo virsh net-autostart default
}}}

{{{#!wiki important
Check [[LXC#Network_setup_in_buster]] for buster specific changes.
}}}

= Create sid container =

Now create the container named debian-sid
{{{
sudo lxc-create -n debian-sid -t download -- --dist debian --release sid
}}}

{{{#!wiki important
For Fedora users, if you are unable to start the sid container,use 'sudo systemctl start lxc.service',  'sudo systemctl start lxc-net.service',   'sudo systemctl enable lxc.service', 'sudo systemctl enable lxc-net.service'  
}}}

You might have to use `lxc-attach` instead of `lxc-console` to connect to the container. After attaching yourself you could set your root password using `passwd`. 

= Using the created container =

Before connecting to the container, you might want to start the container

{{{
sudo lxc-start -n debian-sid
}}}

To connect to the container
{{{
sudo lxc-attach -n debian-sid
}}}

This is assuming that you have named your container 'debian-sid' as per the previous instructions.

 `lxc-attach` would not setup the tty session for other users and ask pass, what that means is, no sudo, if you switch using `su - <username>` (see next step). Use `lxc-console` if you want to use sudo.

{{{#!wiki important
See http://blog.scottlowe.org/2013/11/25/a-brief-introduction-to-linux-containers-with-lxc/ for more info on using lxc.
}}}

= Create normal user =

Create a new user with adduser and switch to that user with su - <username>. See https://www.digitalocean.com/community/tutorials/how-to-add-and-delete-users-on-debian-8. Easiest way to create a user with permission to run sudo would be:
{{{
useradd -m -g sudo <username>
}}}

It is worth noting that you need to install sudo as it does not come default. Also the `-m` tag creates a home folder for the user, this is not trivial and can be skipped.

{{{#!wiki important
Note: You can install sbuild inside the lxc container for clean builds.
