  27     <title>Description</title>
  28     <para>The root filesystem used by the kernel is specified in the boot configuration
  29 file, as always. The traditional <emphasis remap="B">root=/dev/hda1</emphasis> style device
  30 specification is allowed. If a label is used, as in <emphasis remap="B">root=LABEL=rootPart</emphasis>
  31 the initramfs will search all available devices for an ext2 or ext3 filesystem
  32 with the appropriate label, and mount that device as the root filesystem.
  33 <emphasis remap="B">root=UUID=uuidnumber</emphasis> will mount the partition with that UUID as the
  34 root filesystem.</para>

 335             <para><replaceable>keypath</replaceable> is a path to key file to look for. It&apos;s REQUIRED. When <replaceable>keypath</replaceable> ends with '.gpg' it's considered to be key encrypted symmetrically with GPG. You will be prompted for password on boot. GPG support comes with 'crypt-gpg' module which needs to be added explicitly.</para>
 336             <para><replaceable>keydev</replaceable> is a device on which key file resides. It might be kernel name of devices (should start with &quot;/dev/&quot;), UUID (prefixed with &quot;UUID=&quot;) or label (prefix with &quot;LABEL=&quot;).  You don&apos;t have to specify full UUID. Just its beginning will suffice, even if its ambiguous. All matching devices will be probed. This parameter is recommended, but not required. If not present, all block devices will be probed, which may significantly increase boot time.</para>
 337             <para>If <replaceable>luksdev</replaceable> is given, the specified key will only be applied for that LUKS device. Possible values are the same as for <replaceable>keydev</replaceable>. Unless you have several LUKS devices, you don&apos;t have to specify this parameter.</para>
 338             <para>The simplest usage is:</para>
