This is what is currently in the wild for /usr:

mysql> select mnt_pnt,count(*) as cnt from file_systems where mnt_pnt like
'/usr%' group by mnt_pnt order by cnt;

22 rows in set (3.25 sec)

This is out of 1,702,459 submissions of profiles that included filesystem
data.  So about 3% of users have something mounted in /usr and about 2.2%
have /usr mounted directly.
