On this new install, basically, I have /, /boot, /efi, /home and /var on separate partitions. I put /usr on / like most people do nowadays. I guess I can boot without a init thingy but not sure. I'd rather have two entries, one with and one without a init thingy to test with. May do that later on. Dale :-) :-)
