What's with this /u symlink that points to /Users?

There's a symlink in my root directory called u. It points to Users. It looks like it's being created at boot time, but idk if that means anything. I don't remember this being part of a normal macOS install. I don't have access to any other macOS systems, so I can't compare. I'm running Ventura 13.6.6 (22G630) on a 16-inch, 2019 MBP. Last clean install was Monterey 12.0.1 in October 2021.

❯ ls -l /u
lrwxr-xr-x  1 root  wheel  5 Apr 12 15:10 /u -> Users

❯ GetFileInfo -P /u
file: "/u"
type: "slnk"
