Today I successfully upgraded my FreeBSD home nas server from 10.3 to 11.0. This is the final release of version 11.0, though the official announcement is expected to be made on September 28.

Sure, you Linux gurus must be laughing at me to see this post. However, this is my 2nd time needing to remove a user’s password and I had to Google for it!
