bugfix: when LVMlv name contains btrfs none

Description Gene Czarcinski 2014-06-19 17:14:50 UTC 
Description of problem:
This occured on a qemu-kvm virtual systems with muliple disks and multiple installs.

1. If all installs are to LVMlv, then there does not appear to be a problem.

2.  Install Fedora on /dev/vda (btrfs or partition).

3.  Then, on a seond disk (vdb), install Fedora with LVM partitioning (vdb1 is ext4 and swap & root or LVMlvs).  Run grub2-install /dev/vdb so you will be able to boot this directly.  Just in case, run grub2-mkconfig -o /boot/grub2/grub.cfg

4. Reboot selecting the system you installed on /dev/vda.  Run os-prober.

The output will show two entries exactly the same.  There should only be one.

Version-Release number of selected component (if applicable):
os-prober-1.58-7

How reproducible:
certain circumstances (see above)

bugfix: when LVMlv name contains btrfs

The opriginal test for btrfs change for an output of blkd to contain 'btrfs'.  This is changed so that it now looks for 'TYPE="btrfs"'
