Prevent future problems like we earlier with go.mod replace directives (e.g. removing our certstore replace in 6d6cf88d826c or wireguard-go in ea5ee6f87c15fa, both of which were reactions to problems caused by go.mod replace in non-root modules, often because people are using tsnet as a library from another module) Updates #cleanup Change-Id: I766715cfa7ce7021460ba4933bd2fa977c3081d2 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>
