Hello. You recently post a feature request for the interface you are requesting here. Reading the request it seems that granting this interfaces are not enough for now. Can you confirm?
+1 from me for use of block-devices to ms-sys since its clearly required to write the MBR. I am -1 for auto-connect it though since it grants total device ownership to the snap (@Lin-Buo-Ren you did not request auto-connect though, but clarifying just in case). Can other @reviewers please vote?
I would also say +1 for use but -1 for auto-connect, because this is a “dangerous” utility and should be use with caution (as it can render a machine unbootable), so it’s best if the user actively turns on the necessary connection.
