Two and a half years after the publication of release 6.4, the DragonFly BSD 6.4.1 operating system was released, created in 2003 with the purpose of alternative development of the FreeBSD 4.x branch. Among the features of DragonFly BSD, one can highlight the distributed versioned file system HAMMER, support for loading "virtual" system kernels as user processes, the ability to cache data and FS metadata on SSD drives, context-sensitive variant symbolic links, the ability to freeze processes while saving their state on disk, a hybrid kernel using lightweight threads (LWKT).
The DragonFly BSD 6.4.1 release is a corrective one and only fixes some accumulated bugs. For example, an issue in the pkg package manager was fixed, due to which the df-latetest.conf configuration files were deleted during the update. A memory leak in the IDE/NATA driver was fixed, which led to the kernel going into panic state. Problems with working on UEFI-only systems were solved. The ca_root_nss package was updated, which solved problems with pkg working with the Avalon repository over HTTPS.
