I'll try to reproduce the issue here, but you can also do
the following command directly on the guest disk image if you
want to test something:

  time LIBGUESTFS_BACKEND=direct guestfish --ro -a fc21-64.qcow2 -i selinux-relabel /etc/selinux/targeted/contexts/files/file_contexts / force:true

As long as you make sure you use the '--ro' flag, this will not make
any changes to the disk image.

For me that command only takes ~15 seconds to run on a Fedora 21 disk
image with minimal (@Core) packages installed.  I'm using a
RHEL 7.3 host.
