<h2>Description<a class="headerlink" href="#description" title="Permalink to this headline"></a></h2>
<p>The <strong class="command">mkfs.s3ql</strong> command creates a new file system in the location
specified by <em>storage url</em>. The storage url depends on the backend
that is used. The S3QL User&#8217;s Guide should be consulted for a
description of the available backends.</p>
<p>Unless you have specified the <tt class="docutils literal"><span class="pre">--plain</span></tt> option, <tt class="docutils literal"><span class="pre">mkfs.s3ql</span></tt> will ask
you to enter an encryption password. This password will <em>not</em> be read
from an authentication file specified with the <tt class="cmdopt docutils literal"><span class="pre">--authfile</span></tt>
option to prevent accidental creation of an encrypted bucket.</p>
