I just did this (from [1]):

    sudo chown -R $(whoami):admin /usr/local

And not `sudo chown $(whoami):admin /usr/local`. Are both really necessary?

The -R was a bit overkill - what's inside /usr/local should already have had the correct owner - the problem is the owner of /usr/local itself.

The upgrade changes the permissions of all files within /usr/local to root:wheel.

Didn't for me, only /usr/local itself.

I'd say the "-R" might actually be harmful; for example the mysql GPL distribution binaries from dev.mysql.com installs in /usr/local/mysql and you definitively don't want to mess with the database file permissions there.

It might not be "best practice" to let non-homebrew stuff put things in /usr/local, but it happens.

No, only command with `-R` is necessary.
