Should there be a hardlink from `/Users/Users` pointing to `/Users`? This is was my /Users directory looks like. That Users link doesn't seem quite right..

matt@viking Users $ pwd
/Users

matt@viking Users $ ls -lA
total 8
-rw-r--r--   1 root   wheel      0 22 Aug  2015 .localized
drwxr-xr-x+ 11 Guest  _guest   374 11 Nov 18:40 Guest
drwxrwxrwt   5 root   wheel    170 12 Nov 06:42 Shared
lrwxr-xr-x   1 root   admin      6 12 Nov 23:10 Users -&gt; /Users
drwxr-xr-x+ 14 dave   staff    476  2 May 21:59 dave
drwxr-xr-x+ 87 matt   staff   2958  2 May 22:09 matt

matt@viking Users $


You can then of course go on to do silly things like this..

matt@viking Users $ cd Users/Users/Users/Users/Users/Users

matt@viking Users $ pwd
/Users/Users/Users/Users/Users/Users/Users

matt@viking Users $ ls -lA
total 8
-rw-r--r--   1 root   wheel      0 22 Aug  2015 .localized
drwxr-xr-x+ 11 Guest  _guest   374 11 Nov 18:40 Guest
drwxrwxrwt   5 root   wheel    170 12 Nov 06:42 Shared
lrwxr-xr-x   1 root   admin      6 12 Nov 23:10 Users -&gt; /Users
drwxr-xr-x+ 14 dave   staff    476  2 May 21:59 dave
drwxr-xr-x+ 87 matt   staff   2958  2 May 22:09 matt

matt@viking Users $


It doesn't seem like the Users link should be there, there's a good chance I created it myself by accident; I just can't help but think some service or other might be relying on it being there.

Can I just delete it?
There should not be a link like that. If you truly have a hard link, that's something that's a bit self-referential, snake eating it's own tail recursion, so I'd make sure you have a backup if you're not sure you're deleting the correct link.

From your listing - the link count is 1 so it's probably a sym link and not even a hard link - which means it's safer to delete in reality than in theory above.

I would expect a 2 between the permissions lrwxr-x-ry-x and root owner if you had a hard link there.
