    Linux 6.3 Adds Support For Tmpfs IDMAPPED Mounts - Benefits systemd, Kubernetes & More

    Phoronix: Linux 6.3 Adds Support For Tmpfs IDMAPPED Mounts - Benefits systemd, Kubernetes & More

    Introduced to the mainline kernel two years ago with Linux 5.12 was the IDMAPPED mounts functionality that is useful from systemd-homed to containers and other use-cases. Since then more Linux file-systems and software has added support for IDMAPPED mounts and it's being furthered along now with Linux 6.3...

    Wow, a Linux-only feature pushed by Microsoft to benefit systemd I'm grabbing popcorn and settling down to watch the rants and conspiracy theories.

      For more context, it is being pushed by a long term kernel developer who used to work for Canonical prior to this and is the current maintainer of LXC/LXD. Microsoft has plenty of veteran kernel developers (Linux stable series comaintainer for example) and several systemd developers (Lennart and others). They also have developers focused on upstream Python performance and several other key open source projects. Azure is one of their fast growing business units and a majority of customers there use Linux so all of this makes plenty of sense.

        Of course I know all that and I'm one of those who think that having "Microsoft" written on something doesn't automatically make it evil by itself. It was a joke, but I'm willing to bet that we'll get comments that mean it seriously.
