With a symlink, that "data" is the string that shows as the symlink

a file since the inode needs to be set up and written in any case.
systemd is far from the first program to take advantage of this.
Interesting. What about the old running out of inodes on a disc
problem? How did they handle that?
The symlink is using _one_ inode, which is also the number that would be needed for that tiny file. Creating lots of tiny files will also cause the filesystem to run out of inodes long before it runs out of data blocks.
