A fix to supermin is required if you want to use supermin and/or libguestfs with Linux kernel >= 4.13. It does not affect the recently released kernel 4.12. Supermin incorrectly created symlinks in the appliance filesystem, and although this works with earlier kernels a recent change breaks these (incorrect) filesystems. The symptoms you will see are described in this bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1470157 The fix is included in supermin 5.1.18: http://download.libguestfs.org/supermin/ If you prefer to backport the commit which is fairly small and well-contained, it is: https://github.com/libguestfs/supermin/commit/158854e3ba4be7f6b8d81f662dd... There is no need to upgrade libguestfs.
