[lvm-devel] LVM2 ./WHATS_NEW scripts/vgimportclone.sh test ...



CVSROOT:	/cvs/lvm2
Module name:	LVM2
Changes by:	zkabelac sourceware org	2011-09-07 08:31:17

Modified files:
	.              : WHATS_NEW 
	scripts        : vgimportclone.sh 
	test           : t-vgimportclone.sh 

Log message:
	Replace char class :space: with explicit chars
	
	Some major distributions are still using 'mawk' and they are not using
	the latest version - we end here with hidden dependency on the latest
	version of mawk (1.3.4) while i.e. Debian Lenny seems to stay with 1.3.3.
	So we end with completely broken  vgimportclone script on such system.
	
	We would need to check for proper support of :space: and abort build if
	it doesn't work or simplier replace [:space:] with [ \t] which seems
	sufficient to make it work (as can be seen in this patch)
	
	A better fix would be to use command line parameter override - leaving
	as FIXME comment.
	
	This patch makes t-vgimportclone.sh test passing on Lenny.
