# a source of /dev/null creates the file, so it shouldn't exist. Furthermore,

# the reverse of creation is deletion -- hence the next test, which ensures that

# the file is removed if it's empty once the patch is reversed. The size checks

# are scattered throughout to make sure that we didn't get some kind of false

# error, and the first size check is merely a sanity check that should be
|
||||
# trivially true as this is executed in a sandbox.
