Um, yes, because it won't work. The user tools do the I/O of LVM state information to the disk. The kernel LVM module has no concept of how LVM information is stored on disk. > Just trying to see if there is a way (or would make sense) to skip the > ramdisk stage in mounting a root logical volume. Need to re-write (or at least seriously enhance) the LVM kernel code to do this. Sorry.
