Specifically when they got to the Post Installation instructions. The way the headings are arranged makes this look like a completely distinct set of instructions when they're in fact specifically only for the distro provided packages. Had me confused a bit as well since I couldn't figure out how they got the initialization command without the full path as well as non-versioned service names. Seems it just needs to be made more clear that these instructions are ONLY for the distro provided packages.
