preallocate_images=space

fallocate fails with No such file or directory. Not sure how this is supposed to work, but fallocate fails because disk.fallocate_test file does not exist.

Apparently this wasn't clear in the bug report that fallocate expects the file to exist,

http://git.kernel.org/cgit/utils/util-linux/util-linux.git/tree/sys-utils/fallocate.c#n371

This can be validated on the command line,

$ /usr/bin/fallocate -n -l 1 /tmp/test_file.fallocate
