Of course, any Unix-like filesystem has the concept of numerical "user
IDs" built right into it. Each file and directory has two numbers,
representing the user and the group. On a different install, either
you'll have different users "owning" the files, or there won't be a user
or group corresponding to the number (Fedora, for example, starts
numbers at 500, while Ubuntu starts them at 1000).
It's probably a lot easier, for removable disks that have to be
understood on random Linux installs, to use Fat32.
Of course, there's no guarantee that Linux installs will understand
Fat32 or resierfs, especially if anyone's been compiling their own
