I think without a init thingy, it mounts / ro at first, runs the checks and then remounts rw. I think it does the same with /usr. I'm not sure what decides that tho. The last I rebooted, the checks are done within the init thingy for / and /usr, while mounted ro of course. Once / and /usr are in the clear, it swaps from the init thingy and the normal kernel/OS boot starts. I think it checks /home after the init thingy is gone. I think. It's been a while since I rebooted. 167 days so far. The power company is doing a good job of keeping our power going. If I ever redo my setup, /usr will be on / and hopefully no init thingy. With drives and file systems like they are now, it's just not worth the trouble. Dale :-) :-)
