#
# DESCRIPTION:
#	Verify that POSIX mode bits function correctly.
#
#	These tests are incomplete and will be added to over time.
#
#	NOTE: Creating directory entries behaves differently between platforms.
#	The parent directory's group is used on FreeBSD, while the effective
#	group is used on Linux.  We chown to the effective group when creating
#	directories and files in these tests to achieve consistency across all
#	platforms.
#
# STRATEGY:
#	1. Sanity check the POSIX mode test on tmpfs
#	2. Test POSIX mode bits on ZFS
#
