Subject: [PATCH] Fix convert function to support NVMe devices
d9d99f
d9d99f
This is adapted from the patch at
d9d99f
https://bugzilla.redhat.com/show_bug.cgi?id=1019660 , which is against
d9d99f
the now very old version of convert_system_partition_to_system_disk().
d9d99f
d9d99f
As such, it certainly not the right thing for upstream, but should
d9d99f
function for now.
