 * Merge 'merge_into_isocontent' into 'releng_isocontent' (former hardlinks)
   Extend it to use some more demanding directory tree.
   MD5s should be checked. ACLs and xattr (if we are on Linux).
   All file types as of stat(2) should be tested.
 
-* Also check trivial operations like --devices, etc.

+  xorriso -indev file.iso -pvd_info
 
 * We could mark all own stderr messages by a prefix like "===".
