I simply said that it shouldn't be encouraged, with me reason being that it tends to add unnecessary complexity (in violation of the KISS principle [1]). > As per the documentation itself, Code Listing 2.1 is i believe an > example of what is possible, not what we are encouraging users to do. > That doc seems pretty clear that the default is partitioning scheme is > the default /boot,/,swap ... Why should our main installation docs mention a configuration that the vast majority of our users (all?) would be better off without? > And just to confirm, doesn't udev's installation (which is primarily in > /lib) support /usr on a separate partition now, without an initramfs? What's the benefit of having /usr on a separate partition anyway? The only somewhat reasonable explanation that I've heard is so that it can be mounted readonly. If people want that, I think it's perfectly reasonable to expect them to use either an initramfs or a simple linuxrc approach [2] to ensure that /usr is mounted before init starts. For complex configurations like this, we can have a separate page of docs, like the raid+lvm2 page [3], and link it from the main installation docs if we want.
