Add vmtests that boot pairs of gokrazy VMs whose tailscale and tailscaled are minimal builds and check that IP traffic flows between them over WireGuard, so we notice if a minimal build stops doing its one job: build_dist.sh --extra-small (direct path through NATs), that minus NAT traversal (DERP across NATs, direct on a shared LAN), and DERP-only. They found that "tailscale up" built with ts_omit_ipnbus returned before calling Start or EditPrefs, making it a no-op. Fix that, and have it wait for the Running state by polling tailscaled's status instead of watching the IPN bus, so scripts can rely on it as with normal builds. The extra-small feature list moves to featuretags.ExtraSmall so build_dist.sh (via a new "featuretags --extra-small") and vmtest share it. The gokrazy builder gains --output and --go-build-tags flags to build the variant images, and natlabprep --gokrazy prebuilds them all for CI.

# The natlab targets use ../tool/go rather than whatever "go" is on
|

# $PATH so that they match tstest/natlab/vmtest, which rebuilds this

# image from inside "go test". The go command puts its own $GOROOT/bin

# first on the test binary's $PATH, so the in-test rebuild always uses
|
|
# the tailscale/go toolchain. Building with a different toolchain here
|
|
# (as CI did with the runner's stock Go) leaves nothing in the build
|
|
# cache for the test's rebuild to reuse, turning a ~4 second cache-hit
|
|
# rebuild into a multi-minute cold build inside the test's timeout.
