I recently had a problem that involved being dropped into the
emergency shell of the initramfs: the rootfs was on lvm on a raid
array that was not properly detected during boot. I was able to use
mdadm to get the raid going, but I was then not immediately able to
get lvm going because the only readily available lvm command was
/sbin/vgchange, which on it's own was not sufficient.  I remembered
that all the lvm commands are just symlinks to the single lvm binary,
so I just created a link from /sbin/lvm to /sbin/vgchange and was then
able to have access to the rest of the commands, but this seemed like
a bit of unnecessary work.

I would like to propose that links for all lvm commands get created in
the initramfs.  I believe that it would only increase the size of the
initramfs by less than 1kbyte, and would prove very useful in
situations like I describe above.  I assume the needed changes would
only have to be made to /usr/share/initramfs-tools/hooks/lvm2, but
since I am unfamiliar with the initramfs-tools hooks, I am hesitant to
propose a patch myself.

Thanks for maintaining such an important package.
