The patch at http://comments.gmane.org/gmane.linux.kernel.initramfs/2244 
takes care of only the MAC conversion to lower case in the interface 
name.  But the same has to be taken care for BOOTIF also.  This patch 
takes care of changing the BOOTIF to lower case.

Note that sed has been used instead of tr, as dracut does not install tr 
to the initramfs, atleast on RHEL 6.x.
