Adding the tools adds hardly any increase and size, and will make developing LinuxKit+WireGuard considerably smoother.

The `sshd` and `getty` containers have `ip` and `ifconfig` etc as binaries because they are provided by `busybox` which is needed for other reasons, there is no full featured `iproute2` package installed in those environments.\r\n\r\nIn LinuxKit the network configuration is containerised and occurs in the `dhcpcd` container. I would expect that if I needed to do any non-trivial network configuration I would have to either `ctr exec` my way into the dhcp container (which should have the full feature tools installed, I see that right now it does not, this should be addressed, or maybe we want a \"network admin\" container) or that I would need to  add the tools to the login package either on the fly (`apk add`). Or if I were e.g. building a dedicated network appliance image want to create a custom/derived login environment (i.e. custom `getty`/`sshd` image(s)) with a selection of tools relevant to that appliance installed.\r\n\r\nIt is not clear to me why wireguard should be different to that model, i.e. why we shouldn't produce a `pkg/wireguard` which can be included in images which want to use wireguard (at a minimum something under `examples`, but arguments for including in the top-level `linuxkit.yml` too would be of interest). `pkg/wireguard` can both perform necessary start of day configuration and provide a suitable shell environment (perhaps like the `dhcpd` package it would want to be suitable for both `service` and `onboot` use).\r\n\r\nI expressed my views on adding tools to the `sshd` and `getty` containers on both https://github.com/linuxkit/linuxkit/pull/2249 (where the last comment on the previous PR seemed to agree https://github.com/linuxkit/linuxkit/pull/2249#issuecomment-316704398) and on the slack channel. See also e.g. https://github.com/linuxkit/linuxkit/pull/2263#issuecomment-316810820.\r\n\r\nSo, I'm sorry but my feeling is that this PR was merged prematurely and should be reverted while we discuss how this stuff should be properly integrated into LinuxKit.\r\n\r\nTo be clear, I am not arguing against having wireguard as a core part of LinuxKit, but we should properly discuss how to achieve that within LinuxKit's highly containerised model"}}
