func InstallFile(source, target string, mode os.FileMode) (err error)

InstallFile streams source onto target atomically. Large executables are copied rather than buffered in memory.

func SyncDir(path string) error

SyncDir persists a directory entry so newly written names survive a crash.

func SyncFilesystems(paths ...string) error

SyncFilesystems persists every filesystem backing the given paths.

func SyncOpenFilesystems(files []*os.File, syncfs func(int) error) error

SyncOpenFilesystems synchronizes each distinct filesystem once, using open handles that stay valid after teardown removes their paths.

func WriteFileDurable(path string, data []byte, mode os.FileMode) error

WriteFileDurable also persists newly created parent directories, so the written file cannot outlive the directory entries needed to reach it.
