Why is /boot its own partition and not swap? I suspend to swap, so swap has to be as accessible as /boot? Am I going to enlarge swap at some point using LVM tools? Or shrink it? Can you even do that with a swap partition in LVM? So what ARE the values of swap in LVM? One less partition, I would think if you are going duo boot. But if not, again, where is the beef? > Swap performance should be equally good whether it be raw disk, raw > partition, LVM logical volume or even a flat file on today's kernels, > but maybe there is something I am unaware of.
