IIRC the only partition that can't be encrypted with LUKS is /boot, perhaps use TrueCrypt there if you KNOW they are out to get you. TrueCrypt is also useful if you need to share a partition with certain Non-Unix operating systems. You do need to select the LUKS encryption when you do the CentOS install. -- Todd Denniston Crane Division, Naval Surface Warfare Center (NSWC Crane) Harnessing the Power of Technology for the Warfighter
