[archiso] Add /run/archiso/used_block_devices
This list includes block devices of: * Boot medium [archisodevice] (only if no copytoram= is used) * Loop medium [img_dev] (only if no copytoram= is used) * COW space [cowdevice] (only if cowdevice= is used (no tmpfs is used)) * Loop devices used for SquashFS images. * Loop devices used for device-mapper devices (two per each dm-device, one RO{*.fs} and one RW{*.cow}) Signed-off-by: Gerardo Exequiel Pozzi <vmlinuz386@yahoo.com.ar>
