[lvm-devel] LVM2 configure configure.in



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	prajnoha sourceware org	2012-02-20 19:36:28

Modified files:
	.              : configure configure.in 

Log message:
	Check whether udev supports built-in blkid.
	
	Built-in blkid is supported since udev v176 - set the UDEV_HAS_BUILTIN_BLKID
	variable appropriately so we can use it in the rules to call the built-in
	blkid conditionaly.
