image_types.bbclass: use mke2fs -d to create the ext2/3/4 image
We used populate-extfs.sh which invoked the debugfs to create the image, now the mke2fs' option "-d root-directory" can do the same thing, and which is more faster, for example, the core-imag-sato: * In the past: $ time mke2fs -t ext4 rootfs.ext4 real 0m0.249s user 0m0.036s sys 0m0.132s $ time populate-extfs.sh /path/to/rootfs/ rootfs.ext4 real 0m29.355s user 0m10.637s sys 0m5.544s * Now: $ time mkfs.ext4 -F -d /path/to/rootfs/ rootfs.ext4 real 0m6.338s user 0m3.824s sys 0m1.356s More than 25 seconds are saved.
