+* run_all_releng (master script)
+ + figure out how to efficiently search for interesting
    err/warn keywords spewed up by the script or apps it calls.
- + write common configuration facility
 
 * releng_build_isojigdo:
  + finish boot options
 
-* releng_check_isocontent: compare input data against the ISO image content, might be tricky
- -> work in progress

-* Give up existing standard option -clean in favor of:
-  + Option -keep which keeps the test data from being removed after
-    the test.
-  + Option -clean_up which removes the test data without doing another test.
-  + Rule: A test must not overwrite existing data on disk.
-          It rather shall refuse and offer option -clean_up to
-          solve the problem (after skilled examination by the user).
-  + Rule: A test shall remove all files which it has created.
-          Only explicit user orders shall allow test files to persist.
-          These orders may be program arguments or configuration variables.
-  -> see releng/test_hardlinks for an implementation example
+* releng_check_isocontent (WIP) - compare input data against
+  the ISO image content, might be tricky
 
 * Interpreter to read options from config files and sets the variables
