Using a symlink is a terrible idea, and furthermore - why? You can just
set your new dataset mountpoint to be /opt.
To be clear: if you use symlinks, updates expecting it to be a directory
can just remove the symlink and recreate as an empty directory. This was
particularly true in S10; on IPS, I expect that "pkg fix" would not be
happy about them either.

Posting exactly what you did would help understand. Also, you can do a
"find . | sort > file" in each directory and compare the files.
