The new release comes a year after the 6.2.1 version was released. Existing DragonFly BSD 5.x and 6.0 users also have the option of upgrading instead of fresh installation. DragonFly BSD has its roots in FreeBSD 4.8 and was forked in a different direction in 2003. The new version features the addition of support type-2 hypervisors with NVMM alongside many fixes and improvements. A kernel vulnerability that could be exploited locally has also been fixed. There is a long list of small changes that can be found in the official announcement.
To upgrade to DragonFly BSD 6.4.0 from 5.x or 6.0, users with the generic kernel have to change their local /usr/src to 6.4, rebuild, and then upgrade the packages by following the given instructions. Installation images are also available.
DragonFly BSD is an interesting example of an operating system that took the FreeBSD code and took it in a different direction. It is good to see that the development of such projects continues and that they receive timely updates and improvements.
The drivers have been ported from Linux to amd/radeon in the free version, so there should be no major issues. On the other hand, the work that needs to be done is more focused on improving the overall organization of the DragonFlyBSD project, and not so much on GCC.
There are no frills here - just simple and direct use cases without Linux and the bulky ZFS. It is worth noting that LAMP refers to a ZX Spectrum with a backlight for programming in assembler.
It seems that the focus of the discussion is on the challenges and improvements needed for the DragonFlyBSD project, particularly around its organization. The mention of LAMP and programming in assembler suggests a focus on low-level computing and simplicity.
DragonFly BSD is a free and open-source Unix-like operating system that was initially forked from the popular FreeBSD 4.8 in 2003. It was developed with the goal of creating a more scalable and performance-oriented operating system.
One of the key design principles of DragonFly BSD is its focus on multiprocessing and parallelism. The developers aimed to take advantage of modern hardware architectures, such as multi-core processors, by enabling efficient task distribution across cores. As a result, DragonFly BSD offers excellent scalability and can effectively utilize system resources.
Another unique feature of DragonFly BSD is its filesystem called HAMMER. HAMMER (Hierarchy And Mirroring Enabled Repository) is a high-performance file system that incorporates advanced features like instant crash recovery, efficient snapshotting, and real-time mirroring. It provides robust data protection and ensures filesystem consistency.
DragonFly BSD is known for its commitment to stability and security. The development team emphasizes careful code auditing and prompt bug fixes. They also work on minimizing vulnerability exposure and addressing security concerns promptly.
While DragonFly BSD shares some commonalities with FreeBSD, it differentiates itself through its own set of features and enhancements. It has its package management system, known as DPorts, which enables users to easily install and manage software packages.
DragonFly BSD 6.4 is the latest version of the operating system, released by its developers with a focus on bug fixes and improvements. Here are some key highlights of DragonFly BSD 6.4:
1. Support for Type-2 Hypervisors with NVMM: This release introduces the addition of support for type-2 hypervisors using NVMM (NetBSD Virtual Machine Monitor). It allows users to utilize virtualization technology within the operating system.
2. Kernel Vulnerability Fix: A kernel vulnerability that could be exploited locally has been addressed and fixed in this release. This fix enhances the overall security and stability of the operating system.
3. Various Fixes and Improvements: DragonFly BSD 6.4 includes numerous small changes and enhancements that address issues reported by users and improve the performance, reliability, and functionality of the OS.
To upgrade to DragonFly BSD 6.4.0, users with the generic kernel need to modify their local /usr/src to 6.4, rebuild the kernel, and follow the provided instructions for package upgrades. Installation images are available to facilitate the installation process for fresh installations.
This release demonstrates the commitment of the DragonFly BSD development team to maintain and enhance the operating system, providing users with an updated and improved experience.
