The block-devices interface

block-devices provides the ability to perform operations on raw disk block devices (e.g. /dev/sda, /dev/mmcblk0). This interface grants privileged access to the device.

Auto-connect: no
Super-privileged: yes

Requires snapd version 2.37+.

When the plug sets allow-partitions boolean attribute to true, the interface will grant access to individual partition devices (e.g. /dev/sda1, /dev/mmcblk0p1). The plug needs to be declared in the following manner:

plugs:
  block-devices:
    allow-partitions: true

The allow-partitions attribute requires snapd version 2.71+.

Consumers of this interface require a snap declaration for distribution via the Snap Store.
