[lvm-devel] LVM2 doc/example.conf lib/commands/toolcontext ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	mornfall sourceware org	2009-11-30 17:17:12

Modified files:
	doc            : example.conf 
	lib/commands   : toolcontext.c 
	lib/config     : defaults.h 
	lib/log        : log.c lvm-logging.h 
	test           : test-utils.sh 

Log message:
	Optionally abort on internal errors (and leverage this option in the
	testsuite). (This is showing a problem in the pvmove test for me, so I expect
	the tests to start failing -- this needs to be fixed separately though.)
