This is an initial attempt to add Samba to the FreeBSD after major
rewrite of the VFS code in the upstream.
Most of the port development is now carried in:
https://gitlab.com/samba-freebsd
Due to the way how new Samba VFS code is written there is a constrain
that Samba 4.14+ can run only on FreeBSD 13.1+, as it requires support
of the `nodup` option for the `fdesc` file system, as well as it's
presence in the system in general.
https://gitlab.com/samba-freebsd/-/wikis/The-New-VFS
I'd like to thank CyberSecure Pty Ltd. company for their supoort of
the port development and Andrew Walker from iXsystems Inc. for the
patches he created and made available for the Samba4 on TrueNAS.
