Description

This GNU test checks that when mv moves files between partitions, it preserves the hard links.

for example

mkdir dir
touch dir/file
ln dir/file dir/link
mv dir /dev/shm
ls -i /dev/shm/dir

in gnu's implementation, this would give us something like

5018 file  5018 link

notice the inodes are the same, but in uu-mv the inodes would differ

Research direction

Start by locating the mv implementation and its cross-partition handling, then compare its behavior with the GNU part-hardlink test and the shell reproduction in this issue. Done means moving a directory across partitions preserves the shared inode for the original file and hard link, as shown by matching ls -i output.
