#

# This is a tools-level test intended to verify that cp(1) and mv(1)
# do the right thing with respect to ACLs.  Run it as root using
# ACL-enabled kernel:
#
# /usr/src/tools/regression/acltools/run /usr/src/tools/regression/acltools/tools-nfs4.test
#
# You need to have three subdirectories, named nfs4, posix and none,
# with filesystems with NFSv4 ACLs, POSIX.1e ACLs and no ACLs enabled,
# respectively, mounted on them, in your current directory.
#
# WARNING: Creates files in unsafe way.
