title: How change the filesystem or all catalog /etc/ from RO-ReadOnly to RW?
body: <p>I have a question I have a RO filesystem that is readonly. What I need to change in the file fstab in order to be able to edit system files or the all /etc/ directory editing. I can edit only fstab.
   fstab file:</p>
  
  <pre><code>/etc # cat /etc/fstab
  # /etc/fstab: static file system information.
  #
  # &lt;file system&gt; &lt;mount pt&gt;     &lt;type&gt;   &lt;options&gt;         &lt;dump&gt; &lt;pass&gt;
  /dev/root       /              ext2     rw,noauto         0      1
  proc            /proc          proc     defaults          0      0
  devpts          /dev/pts       devpts   defaults,gid=5,mode=620   0      0
  tmpfs           /dev/shm       tmpfs    mode=0777         0      0
  tmpfs           /tmp           tmpfs    defaults          0      0
  sysfs           /sys           sysfs    defaults          0      0
  </code></pre>
