Sorry for the stupid question, but I'm wondering... It sounds like ksm is a boot manager, kind of like grub (on Linux). So, I'm curious... Does it make sense to install it even if I don't plan to use koreader or other reading software? It seems like it could be useful in the case of a bad firmware patch, if it makes it possible to boot into a known good firmware, if something goes poorly. Is that a common/recommended use of it? (Is there maybe a easier solution to get a known good firmware loaded in the case of a bad/looping firmware update)?
