m/p/efivarfs: allow multiple paths in LoadOption

The FilePathList in an EFI LOAD_OPTION technically allows multiple
device paths separated by end of path markers. These additional paths
beyond the first one do not have any standardized function, but some
EFI vendors use them to store data. Currently we fail to parse them
because they contain more than one end of path marker. Fix this by
adding an ExtraPaths field to LoadOption and implementing marshalling/
unmarshalling for it. I chose to use a separate field in the Go
struct because these additional paths do not have the same functionality
as the first one (they are not bootable).

Monogon Monorepo

This is the main repository containing the source code for the Monogon Platform.

This is pre-release software - take a look, and check back later!

Environment

Our build environment is self-contained and requires only minimal host dependencies:

  • A Linux machine or VM.
  • Bazelisk >= v1.15.0
  • A reasonably recent kernel with user namespaces enabled.
  • Working KVM with access to /dev/kvm (if you want to run tests).

Our docs assume that Bazelisk is available as bazel on your PATH.

Refer to SETUP.md for detailed instructions.

Monogon OS

Run a single node demo cluster

Build CLI and node image:

bazel build //metropolis/cli/dbg //:launch -c dbg

Launch an ephemeral test node:

bazel test //:launch -c dbg --test_output=streamed

Run a kubectl command while the test is running:

bazel-bin/metropolis/cli/dbg/dbg_/dbg kubectl describe node

Test suite

Run full test suite:

bazel test -c dbg //...
