It's better to allocate the space up front than for a newcomer to install, learn, find out about LU and realise too late that a spare slice is required. Considering SXCE is on a 2 week release cycle and there aren't any patches, LU is all but essential for any system one doesn't want to take down for the duration of a cold upgrade. More so when you discover something has been broken in the new build. >> Thus the problem: just like the existing defaults, >> what you're >> recommending works well for some but is abysmal for >> others. >> > > And like I wrote before, this is exactly why I believe LU should be left out > of the discussion: it's a customer preference of whether or not to use, but > does not directly affect or hinder the operation of the OS.
