40# DESCRIPTION:
41#	The minimum volume size for swap should be a multiple of 2 pagesize
42#	bytes.
43#
44# STRATEGY:
45#	1. Get test system page size.
46#	2. Create different size volumes.
47#	3. Verify 'swap -a' has correct behaviour.
48#
49# TESTABILITY: explicit
50#
51# TEST_AUTOMATION_LEVEL: automated
52#
53# CODING_STATUS: COMPLETED (2006-12-12)
