Yes, I know what LVM is for and how to drive it. I think it's wonderful software for what it was designed to do, and it's "does what it says on the box" score is way up there with much other good stuff. But I'm not talking about it for users like you and I. I've said over and over in this thread about regular users and you seem to be missing that part; it's the entirety of everything I'm saying here. I didn't say LVM shouldn't be available, I said that installers shouldn't put it up front and centre in the user's face claiming that it's awesome. Your average user has no idea what volume management even is and are completely lost when it comes up. They just have no mental image of what it even could be and a tool that is not understood and not used is not worth installing. -- Alan McKinnon alan.mckin...@gmail.com
