CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac@sourceware.org	2011-09-24 20:54:36

Modified files:
	test           : t-000-basic.sh 
	test/lib       : aux.sh test.sh 

Log message:
	Detect unusable nodes on fs
	
	Test whether nodes could be used on given filesystem where TMP
	dir is being used and skip teardown quicker in fail case.
	(makes the problem quickly obvious if you try to such fs).
	
	Skip teardown_dev if we have not created any devs yet.
	
	and do not mkdir /dev/mapper dir  when LVM_TEST_DEVDIR is set.
	
	Drop this test from t-000-basic.sh.
