@yetiinabox I've not seen anyone installing Koha on FreeBSD (doesn't mean that people haven't though - but it would take some work).
That's mainly as we use Debian packaging (so installing works well with Debian and Ubuntu, LTS releases).
The reason for Debian packaging? Because there are so many dependencies: CPAN modules (lots!), the components that make Koha run - Apache, MySQL or MariaDB, Plack for caching, Zebra (or Elasticsearch/Open Search) for search, and a myriad of other components.
