Linux To Introduce The Ability To Set The Hostname Before Userspace Starts
Linux To Introduce The Ability To Set The Hostname Before Userspace Starts
17 Hours Ago - Linux Kernel - Linux Kernel hostname= - 14 Comments

While the hostname on Linux systems is widely relied upon for different applications, setting the hostname is usually left up to user-space by the init system at boot. However, should any user-space processes try to read the system hostname prior to it being set, it could lead to unintended results. So now finally in 2022 there is a kernel parameter working its way upstream with "hostname=" should you want to ensure the hostname is set before user-space is started.

Last week I wrote about how well known Mesa developer Samuel Pitoiset who is employed by Valve already started working on GFX11 (RDNA3) support for RADV, the open-source Radeon Vulkan driver in Mesa that isn't officially supported by AMD but remains more popular than their own "AMDVLK" driver. More GFX11/RDNA3 preparation work remains ongoing and it's looking like if trends continue this open-source driver could be ready for RDNA3 graphics cards in time for launch.

Back in 2017 for the Linux 4.11 kernel the statx system call was added for allowing enhanced file information reporting. Since then various file-systems began adding Statx support and worked its way up into Glibc and the like in user-space for Linux finally having file creation time reporting and other attributes. Two separate statx-related additions are now working their way to the kernel.

Mesa's Radeon Vulkan driver "RADV" continues working on maturing its ray-tracing implementation after the initial code was merged last year. RADV ray-tracing is still treated as experimental and not as reliable as the proprietary NVIDIA Vulkan driver's ray-tracing support that has been around much longer, but it's getting there and at least is open-source -- unlike AMD's official AMDVLK driver that continues to not support Vulkan RT unlike their proprietary driver alternative.
