Good. The currently-proposed initramfs-tools patchset already fscks
everything it mounts, and I hope nobody is going to propose a patchset
that does otherwise.

I'll try to do that at some point, but I will be delighted if someone
else comes up with a patch sooner.

Great. Then switching to fsck -M does not block the other bugs, and
initscripts/systemd redundantly fsck'ing a root filesystem that is
already (intentionally) mounted ro shouldn't be a problem.

Or turned into "use fsck -M instead of fsck -R" and reassigned to
initscripts, yes.

Sorry, yes, "monolithic" was a poor choice of shorthand there.
