Function ro_partition in /usr/share/os-prober/common.sh makes a partition read-only. This is called in /usr/lib/os-probes/50mounted-tests before trying to mount the partition being probed with all possible fs-types. Obviously this will break all other processes trying to write to this partition at that time.
