Yes, you are right - I read too hastily.

Something wrote to the md device despite it being marked 'read-only'.
Some filesystems do that to replay their journal.  totally inexcusable
behaviour, but what can we do....

I'm surprised that would happen during installation though.
But certainly the array is marked read-only, and certainly something is
writing to it, and that is the real bug.
