I assume you mean `package-vc-install' (as you mentioned in the
subject).

This looks pretty similar to the results on my own system, I also have a
eat.info file that is 119891 byte large.  What I noticed though is that
if I had an info root node buffer lying around, the buffer wasn't
updated so I had to kill and re-create it.

Installing eat using package-install appears to give me a eat.info byte
large file, but that might just be a different version of the manual.
Otherwise it behaves the same -- the important part is that just
installing a package and downloading it using
package-vc-install/checkout gives us the same layout.  The manual
"activation" is still handled by package.el.
