LVM and filter out eMMC


@pcfe @Ondrej_Caletka - I’m setting up a raid 1 whole pv md (sda + sdb using mdadm) and have run into similar issues with LVM as described here: Logical Volumes (LVM): safe to filter /dev/mmcblk0rpmb?

I’ve added filter, fixed, but will I experience issues when Turris OS updates? Do I need to do anything to preserve the filter line in the conf?
