** Description changed:

- after upgrade to 4.13.0-26-generic #29~16.04.2-Ubuntu all the virt-*
- tools not work anymore
+ (Updated Description/Summary)
+ 
+ Summary
+ ==========
+ * This is a bug in the supermin package v5.1.14 in Xenial.
+ * This bug affects supermin versions < v5.1.18 when using a
+   kernel that is v4.13-based or later.
+ * This bug was caused by an update to the mainline v4.13 kernel
+   which broke supermin due to the way supermin handled symlinks.
+ 
+ Impact
+ ========
+ * The bug results in total loss of functionality in supermin
+   and users of supermin such as guestfish, libguestfs-test-tool,
+   others. i.e. it is a regression in functionality for managing
+   virtual appliances.
+ * This bug does not affect Bionic, Artful or Trusty (See Comment #14).
+ 
+ Test Case & Reproduction
+ ===========================
+ * This bug manifests in different ways based on the caller / use case
+   but is reliable and consistent in its reproduction.
+   See original description and Comment #12, for trivial repro cases.
+ 
+ Fix
+ ====
+ * The fix for the Xenial version includes a backport of 2 upstream
+   fixes to the file ext2fs-c.c (the fix for the symlink breakage
+   is contained in this file). See comment #13 for details.
+ * A separate PPA test package for Xenial is available to test with
+   (See comment #13).
+ * This fix has been tested successfully on Xenial and shown to fix the
+   reported and related breakages as listed in this bug (Comment #12).
+ 
+ Regression Potential
+ =====================
+ * Regression Potential: there might be some bugs in some edge cases
+   that have not been tested or some environment that is not typical
+   causing some new issue which might affect the creation of the virtual
+   appliances and their management/manipulation via tools in the
+   libguestfs-tools package (e.g. guestfish).
