增加 vm.max_map_count 的默认值

系统参数 vm.max_map_count 的默认值将从 65530 增加到 1048576
这一变更应该能对一些内存需求较高的应用程序帮助改善性能,减少崩溃或者启动问题,尤其是(但不仅限于)通过 Wine/Steam Proton 玩一些 Windows 游戏的情况。总体上来说,用户应该得到更平滑的开箱使用体验,而目前没有已表明的潜在顾虑,参见 arch-dev-public 邮件列表上关于本提议的讨论
这项对 vm.max_map_count 的修改将会增加到 2024.04.07-1 版本的 filesystem 包,并且将在更新后生效。
在更新系统前,如果你已经在 sysctl.d 文件中自己设置过这个参数,请要么删除它(来切换到新的默认值),要么确保你的配置文件会比 /usr/lib/sysctl.d/10-arch.conf 文件有更高的优先级(以覆盖新的默认值)。
