Log Message:
	Extend the original file before to the new size before updating it.
	Instead of opening the original file for writing w/ tuncation, we
	first extend the file with zeroes (by writing, not seeking), then
	overwrite it.  This should allow sudo to fail early if the disk is
	out of space before it overwrites the original file.
