LayerFS gives AI coding agents a shared history file system
What happened
On October 21, Hacker News featured LayerFS, a file system built for AI coding agents. Each agent can mount a writable scratch workspace and commit changes to a shared, persistent history. File tool calls and Bash calls create checkpoints, and you can fork from any commit. Conflicts on the same file are rejected by default, though a /.lww rule lets the newer change win. Dependencies and ignored files stay in the commit. The page's comparison says install takes about 5 minutes and mounting 0.05 seconds; deduplication, compression and storing only changed bytes cut storage overhead.

LayerFS 为 AI 编码智能体提供文件系统，每个智能体挂载可写的临时工作区，并将修改提交到共享的持久历史。文件工具调用和 Bash 调用形成检查点，支持从任意提交分叉，同文件冲突默认拒绝，也可用 /.lww 规则让较新的修改胜出。依赖与被忽略的文件保留在提交中，页面对比安装约需 ~5 min、挂载仅需 0.05 s，并通过去重、压缩及仅保存修改字节减少存储开销。
