Eh, just mount a tmpfs for /var, and an overlayfs for /etc (backed by a tmpfs).
I see that this thread is one massive communication failure on my part :(
I wrote about "booting successfully with a read-only file system", but I
see that I didn't say "... when the disk cannot be mounted rw because of
file system errors". I thought it'd be clear from the context, but it's
clearly not. Anyway, while I'm a big fan of coreos and read-only-on-purpose,
I was writing about traditional systems in a read-only-by-accident scenario,
i.e. about the system behaving gracefully when the disk is ***unexpectedly***
PS. OK, I know I wrote about making it read-only on purpose using a
kernel commandline option, so really we're just pretending it was
unexpected for testing purposes, but you get what I mean I hope.
