Is it possible to setup Fedora, using Fedora provided tools/software,

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.
If I'm not mistaken, /var needs to be on that partition and needs to be writable.
it is not uncommon to have /var on a own partition
If so, then you can't have a
read-only root partition.
it works, but be really carefull
And, just so we all know where we're going here, why would you want to?
in theory more security
imagine a root-exploit changing a system binary
much more difficult if the rootfs is readonly
Extra security is certainly a plus. My main reason for wanting to
run a read-only root it to avoid wearing out the consumer grade
compact flash card that I'm using as my root device (yes, I'm
cheap).
