→‎Install all these finally: /vz/private creation for tmpfs on it later

<pre>

# rm root/root/.bash_history

</pre>

Here we have to make one step to workaround [[Checkpointing and live migration]] problem. The thing is that at the moment

chekpointing isn't supported on <tt>unionfs</tt> filesystem ([http://bugzilla.openvz.org/show_bug.cgi?id=606 Bug #606]).

But we want of course checkpoiting to work on LiveCD. If we mount <tt>tmpfs</tt> on <tt>/vz/private/</tt> on '''booted''' LiveCD,

then all newly created VEs reside on <tt>tmpfs</tt> and checkpointing works. Moreover we do not introduce any additional memory usage,

because even without <tt>tmpfs</tt> all VEs reside in RAM (they contain new/updated files for <tt>unionfs</tt>).

Create <tt>/vz/private</tt> directory, later, while modifying initrd image we will add the line that will mount <tt>tmpfs</tt>

on this directory:

<pre>

mkdir root/vz/private/

</pre>

'''Booted''' LiveCD filesystem is ready, congratulations!
