not sure  as I am just learning 


...but suppose 
I have already mounted   proc, run and sys  
and I want just a read only root filesystem 

--a)  how do  I get  systemd to mount a   nonRW  root filesystem    and not 
bother with anything  in fstab.?  OR
--b) could I  have  an fstab  with  /  -o,ro?
( and if so what would systemd-remount-fs.service do ?)


thanks in advance
sincerely
