Bug 676405

+++ This bug was initially created as a clone of Bug #676404 +++

When running in the rescue shell, the normal lvm command symlinks are not present as in a normal environment or even in the chrooted / filesystem environment.  Because of this, users recovering their systems by booting into the rescue shell have to type "lvm" to preface each command, for example, "lvm pvs" instead of just "pvs".  It should be a simple fix to add these symlinks into the rescue shell.

Note this is in the rescue environment's shell (rather than the chroot-ed / filesystem).  If you choose 'skip' on the options to mount linux filesystems then you will not be able to run pv/vg/lv commands without prefacing them with "lvm ".

Below are probably all the symlinks needed.  Note that this was taken from a booted RHEL6.0 system.  The only difference from a rescue environment I think should be the symlinks should be in /usr/sbin in the rescue shell.
