testload
--------
- Command: testload file
Read the entire contents of FILE in several different ways and
compares them, to test the filesystem code. The output is somewhat
cryptic, but if no errors are reported and the final `i=X,
filepos=Y' reading has X and Y equal, then it is definitely
consistent, and very likely works correctly subject to a
consistent offset error. If this test succeeds, then a good next
step is to try loading a kernel.
