# -----
# minimal access ACL has ACEs: USER_OBJ, GROUP_OBJ, OTHER_OBJ
# This is set with chacl(1) and can be changed by chmod(1).
#
# Test that this is being set for ACL and for std unix permissions
# Test that we can get back the same ACL.
# Test std permissions for rwx.
# -----
#
# Test out default ACLs and that the ACL is being PASSed
# onto the children of the dir.
#
# -----
# Test out access check for extended ACLs.
# -> 3 extra ACEs: MASK, GROUP, USER
# -> the GROUP compares with egid of process _and_ the supplementary
#    groups (as found in /etc/group)
#
# Test that mask works for USER, GROUP, GROUP_OBJ
# Test that the ACE type priority is working
#   -> this would be done by simultaneously matching on ACEs
#   -> interesting if it allows user to specify ACEs in any order
