style='font-size:10.0pt;font-family:Arial;color:navy'>It means that if your
root filesystem resides on the LVM partition, the kernel will need the LVM
subsystem activated before mounting the root filesystem. Of course, this means
that the activation should be made without using the root filrsystem or
anything on it. Therefore, the LVM activation should be done from the initrd
image (and the image should be appropriately made for that purpose), because it
is passed to the kernel by bootloader and is accessible without the need for
the root filesystem.<o:p></o:p></span></font></p>

root on LVM requires an initrd image that activates the root LV. If a kernel is
upgraded without building the necessary initrd image, that kernel will be
unbootable. Newer distributions support lvm in their mkinitrd scripts as well
as their packaged initrd images, so this becomes less of an issue over time. <br>
