  • University of Toronto ☛ A silly systemd wish for moving new processes around systemd units

    Linux cgroups offer a bunch of robust features for limiting resource usage and handling resource contention between different groups of processes, which you can use to implement things like per-user memory and CPU resource limits. On a systemd based system, which is to say basically almost all Linuxes today, systemd more or less completely owns the cgroup hierarchy and using cgroups for resource limits requires that the processes involved be placed inside relevant systemd units, and for that matter that the systemd units exist.

      Hello everyone,
      
      
      The bugfix release 25.1.3 is now available.
      
      
      This is an emergency release, out of the normal schedule, to fix
      a regression for AMD GFX12 (RDNA4) users who have an old firmware.
      
      
      The next bugfix release is still due at the previously scheduled date,
      on June 18th.
      
      
      Cheers,
        Eric
