## 16. `cmd/ns` and `cmd/xtcp2` do not link outside nix — `giouring` / `syscall.munmap` — OPEN
## 16. `cmd/ns` and `cmd/xtcp2` do not link outside nix — `giouring` / `syscall.munmap` — DONE 2026-11-07

**Resolved:** the fork replaced the linkname with direct mmap/munmap syscalls
(randomizedcoder/giouring ab1091f, in v1.0.1). xtcp2 now requires the fork's
`main` as `github.com/randomizedcoder/giouring v1.1.2`, with no `replace`, so
a plain `go build ./...` links and `-ldflags=-checklinkname=0` is gone.
nix builds from the same module, which drops `nix/lib/patchGoMod.nix` and the
`giouring` flake input. The original notes follow.

A plain `go build ./cmd/...` in a working tree fails:
