mkfs.btrfs does not handle relative pathnames for now. When
they are passed to it it creates empty image. So first time
I thought it does not work at all.
This patch adds error handling for scandir(). With patch it behaves
this way:
$ mkfs.btrfs -r ./root
...
fs created label (null) on output.img
nodesize 4096 leafsize 4096 sectorsize 4096 size 256.00MB
Btrfs v0.19-52-g438c5ff-dirty
scandir for ./root failed: No such file or directory
unable to traverse_directory
Making image is aborted.
mkfs.btrfs: mkfs.c:1402: main: Assertion `!(ret)' failed.
