A) Can I ask why it's got a read-only filesystem?
Because it will lose power occasionally and I'm trying to avoid corrupted filesystems.
(It's actually a data logger, so it has a read-write data partition but a read-only O/S partition. That means I can generally symlink various files to the read-write partition as needed, but some things still make life difficult, like deleting and recreating files - or rather failing to).
Possibly irrelevant, but there are UPSes and Battery backup systems that you can plug in to a Pi, or even Power Over Ethernet. e.g. https://www.pi-supply.com/product-category/power-supplies-and-batteries/
Just included it in case it helps.
