That's the standard patrh, though they can go anywhere.

You can certainly do it that way, but why not just  mount the
partition as /usr/src and do away with the symlink?   That's cleaner,
and generally better - mounting things in the root directory (including /mnt)
can cause even worse problems than should occur should the device
holding the mounted filesystem ever hang (refuse to do anything, either
dur to software or hardware issues).
