func SameFilesystem ¶

func SameFilesystem(path1, path2 string) (bool, error)

SameFilesystem checks if two paths are on the same filesystem. This is required for hardlinks, which cannot span filesystems. Returns true if both paths are on the same filesystem, false otherwise. Returns an error if either path doesn't exist or cannot be accessed.

Implementation is platform-specific:

• Unix: compares device IDs from stat(2)
• Windows: compares volume serial numbers
