This change should help addressing performance, crash or start-up issues for some memory intensive applications, particularly for (but not limited to) [some Windows games](https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2057792/comments/5) played through Wine/Steam Proton. Overall, it goes forward a smoother user experience out of the box with no expressed concerns about potential downsides in the related proposal. This `vm.max_map_count` increase is introduced in the `2024.04.07` release of the [filesystem package](https://archlinux.org/packages/core/any/filesystem/) and will be effective right after the upgrade. Before upgrading, in case you're already providing your own value for that parameter in a `sysctl` config file, either remove it (to switch to the new default value) or make sure your config file will be read [with a higher priority](https://man7.org/linux/man-pages/man8/sysctl.8.html#SYSTEM_FILE_PRECEDENCE) than the `/usr/lib/sysctl.d/10-arch.conf` file (to supersede the new default value). -- Regards, Robin Candau / Antiz
