This patch finalizes the block device refactoring. It moves the three remaining levels (filesystem creation, mount and fstab handling) into the new python module. Now it is possible to use any number of disk images, any number of partitions and used them mounted to different directories. Notes: * unmount_dir : modified to only unmount the subdirs mounted by mount_proc_sys_dev(). dib-block-device unmounts $TMP_MOUNT_PATH/mnt (see I85e01f3898d3c043071de5fad82307cb091a64a9) Change-Id: I592c0b1329409307197460cfa8fd69798013f1f8 Signed-off-by: Andreas Florath <andreas@florath.net> Closes-Bug: #1664924
