You may be right. I recall at least / being done during the init thingy part. I thought /usr was to, since it is mounted along with / within the init part before the regular OS boots. That's my understanding of the purpose of the init thingy is to mount / and /usr and then pivot over to the regular boot process. Maybe it mounts /usr ro or something. Yea, it used to be recommended and in a way it can still be a good idea. I use LVM for example and I can increase /usr, /var, /home or whatever without having to redo my drive setup. The only thing I can't change is / which is a regular file system. Just have to cross that bridge when I get there. Oh, I had a log file file up /var once. System was still running and I was able to figure out the problem before it got worse. I can't recall what the problem was now but messages was huge, I mean HUGE. Dale :-) :-)
