For example, we have two filesystems, one is embedded into another:
/a/test # first filesystem with a directory "/a/test/b2"
/a/test/b2 # not auto mounted yet second filesystem, notice "/a/test/b2" is
# a new directory on this filesystem after this filesystem is mounted
For subpath mount "/a/test/b2", `openat("/a/test", "b2")` gets directory "b2" on the first
filesystem, then "mount -c" will use this wrong directory as source directory.
`fstatat("/a/test", "b2/")` forces triggering auto mount of second filesystem, so
`openat("/a/test", "b2")` gets correct source directory for "mount -c".

1. https://man7.org/linux/man-pages/man2/openat.2.html
If pathname refers to an automount point that has not yet
been triggered, so no other filesystem is mounted on it,
then the call returns a file descriptor referring to the
automount directory without triggering a mount.
2. https://man7.org/linux/man-pages/man2/open_by_handle_at.2.html
name_to_handle_at() does not trigger a mount when the final
component of the pathname is an automount point. When a
filesystem supports both file handles and automount points, a
name_to_handle_at() call on an automount point will return with
error EOVERFLOW without having increased handle_bytes. This can
happen since Linux 4.13 with NFS when accessing a directory which
is on a separate filesystem on the server. In this case, the
automount can be triggered by adding a "/" to the end of the
pathname.
Some operations with Azure Disk volumes can be arbitrarily slow
sometimes. This causes CI flakes that are hard to debug.
Bumping the timeouts has sown to improve or eliminate this issue.
Ginkgo has been migrated to V2, add this to unwanted dependencies
so that it won't be shown up as a dep again in the future.

The alias for vendor/github.com/onsi/ginkgo/ginkgo ensures that code like
30e99cb2a9/experiment/kind-conformance-image-e2e.sh (L110)
continues to work. The one without "vendor/" is there just in case that it
was used because it also worked.
Long term, "ginkgo" is a nicer, version independent alias. It gets used
internally to avoid future churn and gets documented also publicly in the
Makefile help.
The caveat is that there's no guarantee that a future v3 CLI will be compatible
with current invocations. But the most common usage is through
hack/ginkgo-e2e.sh, which can deal with such differences.
Ginkgo is now writing the JUnit file itself. The -report-dir parameter is used
as fallback for enabling JUnit output in case that users haven't migrated to
the new -junit-report parameter.

Besides, the using of method might lead to a `concurrent map writes`

Default timeout setting has been reduced from `24h` down to `1h` in
Ginkgo V2, but for some long running test this is too short.
How long to abort the test was controlled by the the linux command `timeout`
in V1. e.g. `'timeout -k 30s 150m ...`, and is configured in the file
like `sig-network-misc.yaml`.
Set the timeout manually for Ginkgo V2 to avoid the early aborting.

The change is needed for `verify-e2e-test-ownership.sh`.
The `jq` is re-defined since the structure of test spec
is different with v1 and the stacktrace related validation
is not available, e.g. `package` and `func`.

`FullStackTrace` is not available in v2 if no exception found
with test execution.
The change is needed for conformance test's spec validation.

The change is needed to verify the conformance test spec, as this
is verified in `verify-conformance-yaml.sh`.

Full stack traces are on by default. The approach for collecting results is
different. Tests run in their own goroutine, therefore runTests is no longer
part of their callstack. To cover stack traces with more than one entry, a new
test case gets added with a separate helper function.
Gomega object formatting now includes the type.
This removes the last remaining reference to Ginkgo v1.
