There was a patch trying to fix this problem by using 'dirname', but it caused some build failures, thus got reverted.

The problem is that $DIR might be empty and we should first do the check before trying to use $(dirname $DIR).

[YOCTO #5712]

Previously, even if we encounter some error when populating the ext filesystem, we don't error out and the rootfs process still succeeds.

However, what's really expected is that the populate-extfs.sh script should error out if something wrong happens when using `debugfs' to generate the ext filesystem. For example, if there's not enough block in the filesystem, and allocating a block for some file fails, the failure should not be ignored. Otherwise, we will have a successful build but a corrupted filesystem.

The debugfs returns 0 as long as the command is valid. That is, even if the command fails, the debugfs still returns 0. That's really a pain here. That's why this patch checks the error output to see whether there's any error logged.
