   5 # We test a couple of things here, using the rmibtest service and test87:
   6 # - some cases where remote MIB subtree registration should fail;
   7 # - a new mount point (minix.rtest) with a small tree behind it, on which we
   8 #   test some basic reads and writes on an integer pointer and a function;
   9 # - shadowing of an existing subtree (minix.test) with a similarly looking
  10 #   subtree, which we then subject to a subset of test87;
  11 # - resource accounting, making sure everything is the same before and after.
