As a warm-up to making natlab support multiple operating systems,
start with an easy one (in that it's also Unixy and open source like
Linux) and add FreeBSD 15.0 as a VM OS option for the vmtest
integration test framework, and add TestSubnetRouterFreeBSD which
tests subnet routing through a FreeBSD VM (Gokrazy → FreeBSD →
Gokrazy).
Key changes:
- Add FreeBSD150 OSImage using the official FreeBSD 15.0
BASIC-CLOUDINIT cloud image (xz-compressed qcow2)
- Add GOOS()/IsFreeBSD() methods to OSImage for cross-compilation
and OS-specific behavior
- Handle xz-compressed image downloads in ensureImage
- Refactor compileBinaries into compileBinariesForOS to support
multiple GOOS targets (linux, freebsd), with binaries registered
at <goos>/<name> paths on the file server VIP
- Add FreeBSD-specific cloud-init (nuageinit) user-data generation:
string-form runcmd (nuageinit doesn't support YAML arrays),
fetch(1) instead of curl, FreeBSD sysctl names for IP forwarding,
mkdir /usr/local/bin, PATH setup for tta
- Skip network-config in cidata ISO for FreeBSD (DHCP via rc.conf)
