USAGE:
$0 [-hvqxkfS] [-s SIZE] [-r RUNFILES] [-t PATH] [-u USER]

DESCRIPTION:
	ZFS Test Suite launch script

OPTIONS:
	-h          Show this message
	-v          Verbose zfs-tests.sh output
	-q          Quiet test-runner output
	-x          Remove all testpools, dm, lo, and files (unsafe)
	-k          Disable cleanup after test failure
	-f          Use files only, disables block device tests
	-S          Enable stack tracer (negative performance impact)
	-c          Only create and populate constrained path
	-R          Automatically rerun failing tests
	-n NFSFILE  Use the nfsfile to determine the NFS configuration
	-I NUM      Number of iterations
	-d DIR      Use DIR for files and loopback devices
	-s SIZE     Use vdevs of SIZE (default: 4G)
	-r RUNFILES Run tests in RUNFILES (default: ${DEFAULT_RUNFILES})
	-t PATH     Run single test at PATH relative to test suite
	-T TAGS     Comma separated list of tags (default: 'functional')
	-u USER     Run single test as USER (default: root)

EXAMPLES:
# Run the default (linux) suite of tests and output the configuration used.
$0 -v

# Run a smaller suite of tests designed to run more quickly.
$0 -r linux-fast

# Run a single test
$0 -t tests/functional/cli_root/zfs_bookmark/zfs_bookmark_cliargs.ksh

# Cleanup a previous run of the test suite prior to testing, run the
# default (linux) suite of tests and perform no cleanup on exit.
$0 -x
