Re: Some information that git diff saves and that git status does not

I didn't fully read what you wrote but after you copy a repository from
one to another outside git (be it done with unison or rsync), you should
run "update-index --refresh".

And the reason for this is that git also looks at the inode numbers, and I
guess that unison does not go as far as to preserve them between machines...

True; we used to (and you can still configure git to) check st_dev too but
we stopped to doing that by default as it is unstable even in a normal use
case (read: no "cp" involved) on some networked file systems.

I wonder how stable inum is on inode-less filesystems (say FAT).  I guess
it is not usually a problem because carrying repositories on USB keychains
is typically done as a sneakernet and with bare repositories.
