help FreeBSD FAQ

What is FreeBSD, and when did it begin?

FreeBSD is an open-source Unix-like operating system whose first official release appeared in 1993. It is developed as a complete operating-system project rather than only as a kernel.

How is FreeBSD different from a typical Linux distribution?

FreeBSD develops and distributes its kernel, userland, documentation, and base system together, while Linux distributions combine the Linux kernel with projects from many sources. FreeBSD also uses a permissive BSD license and provides both packages and the Ports Collection.

What are FreeBSD jails used for?

Jails isolate processes, files, users, and networking within a FreeBSD host, making them useful for lightweight service separation. The jail concept dates back to FreeBSD 4.0, released in 2000.

Does FreeBSD support ZFS?

Yes, FreeBSD includes OpenZFS support for pooled storage, snapshots, checksums, and other data-management features. The FreeBSD Handbook documents both ZFS administration and alternatives such as UFS.
