Is it possible to setup read-only root ?

[John Wendel]

Is it possible to setup Fedora, using Fedora provided tools/software, 
with a read-only root partition?

There's an ancient wiki entry from the FC6 days that indicates that some 
work was done, but I would assume that this depended on the SysV init 
system. I've haven't seen any mention of read-only root setup with systemd.

Any clues would be greatly appreciated.

Thanks,

John
