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.

This is the init style used by the Linux distribution (or other operating system) being used\&. This is usually determined dynamically by checking the system\&. This variable is used by the initscript to determine which init system primitives to use\&. It is also used by some eventscripts to choose the name of initscripts for certain services, since these can vary between distributions\&.

CTDB can use a lot of file descriptors, especially when used with Samba\&. If there are thousands of smbd processes connected to CTDB when this can mean that thousands of file descriptors are used\&. For CTDB, it is often necessary to increase limit on the maximum number of open files\&.

The maximum number of open files should be configured using an operating system mechanism\&.
