Owners and groups are actually numbers UIDs and GIDs - always.  The
text is just a label for humans.
So, if a file is owned by user 500, it checks the /etc/passwd file,
and sees user 500 has name 'fred' and displays 'fred' on the screen.
If you take that drive to another computer that doesn't have a user
500, it just prints 500.  If that other computer has a user 500 called
john - it prints John on the screen.

Perhaps it would be helpful to create a group called 'gitusers' or
something, with a specified group number of say 5555 or whatever on
every computer you want to hook that drive up to.
