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