  52
  53 That means that no eventscripts can be tested.
  54
  55 One possible explanation:
  56
  57   You have CTDB installed via RPMs (or similar), so the regular
  58   CTDB_BASE directory is in /etc/ctdb/
  59
  60   BUT
  61
  62   You have done a regular "configure" and "make install" so the tests
  63   are installed under /usr/local/.
  64
  65 If so, one possible hack to fix this is to create a symlink:
  66
  67   ln -s /etc/ctdb /usr/local/etc/ctdb
  68
  69 This is nasty but it works...  :-)
