-// ^-- Note: This will eventually move to the public /sys package. It is
-// experimental until we audit the socket related APIs to ensure we have all
-// the Errno it returns, and we export fs.FS. This is not in /internal/sys as
-// that would introduce a package cycle.
-
-// This is a subset of errors to reduce implementation burden. `wasip1` defines
-// almost all POSIX error numbers, but not all are used in practice. wazero
-// will add ones needed in POSIX order, as needed by functions that explicitly
-// document returning them.
