FreeBSD
FreeBSD is UNIX-like open source OS software. In particular, its performance as a network operating system exceeds that of Linux-based systems, and it maintains stable performance even under high loads.
FreeBSD is designed to be robust and sturdy with an emphasis on practicality, making it suitable for operating FTP, WWW, and e-mail servers for major companies and services
On December 2, 2025, the latest release version of FreeBSD, FreeBSD 15.0-RELEASE, was made available.
FreeBSD 15.0 introduced a new method for installing and managing the base system using the pkg package manager.
This method is called "pkgbase," and the base system is installed as a package set from the FreeBSD-base repository.
The installed system is fully managed by the pkg tool.
pkgbase will be used as the default installation method in FreeBSD 16 and later, for all VM images and images published to public clouds.
Install
1.Download the installation image
Access the FreeBSD distribution site (https://www.freebsd.org/where/) and select amd64.
Select "FreeBSD-15.0-RELEASE-amd64-dvd1.iso" and download it.
2.Create boot disk
Create a boot disk (DVD disc) from the downloaded FreeBSD-15.0-RELEASE-amd64-dvd1.iso
To create a USB memory stick, download FreeBSD-15.0-RELEASE-amd64-memstick.img and use an image writer such as Win32 Disk Imager to create it.

9.Select Installation Type
①Distribution Sets （conventional method）
Distribution Set (Conventional Method)：This is the method used in previous FreeBSD releases. Systems installed using this method will continue to use the freebsd-update utility for updates. Support for the distribution set is scheduled for removal in FreeBSD 16, but will continue (along with freebsd-update support) for the duration of the FreeBSD 15 stable branch.
➁Packqges (Tech Preview) (pkgbase / New method)
Package (pkgbase / new method): The base system is installed as a package set from the "FreeBSD-base" repository. Systems installed this way are fully managed using the pkg tool.
This method is used by default for all VM images and images published to the public cloud. In FreeBSD 15.0, pkgbase is provided as a Technology Preview, but it is intended to become the standard method for managing base system installation and upgrades in future releases.
This time, we will use the conventional installation method (Distribution Sets).
