[pkg-cryptsetup-devel] Bug#419571: Patch to mkinitramfs hook

[Doug Huff]

The output from lvs isn't any simpler to parse really. This has the  
same limitations as the existing implementation in regards to devices  
moving so nothing is worsened with this patch.

I didn't see a reason to completely reimplement the whole method for  
detecting lvm devices to get this bug that prevents booting in a very  
common use case fixed.
