In the CI, test containers intermittently fail to start after creation,
with an error like below (see #10872 for more details):
# State: Terminated
# Reason: StartError
# Message: failed to start containerd task "afd43e77fae0815afbc7205eac78f94859e247968a6a4e8bcbb987690fcf10a6": No such file or directory (os error 2)
I've observed this error to repro with the following containers, which
have in common that they're all *very short-lived* by design (more tests
might be affected):
* k8s-job.bats
* k8s-seccomp.bats
* k8s-hostname.bats
* k8s-policy-job.bats
* k8s-policy-logs.bats
Furthermore, appending a `; sleep 1` to the command line for those
containers seemed to consistently get rid of the error.
Investigating further, I've uncovered a race between the end of the container
process and the setting up of the cgroup watchers (to report OOMs).
If the process terminates first, the agent will try to watch cgroup
paths that don't exist anymore, and it will fail to start the container.
The added error context in notifier.rs confirms that the error comes
from the missing cgroup:
https://github.com/kata-containers/kata-containers/actions/runs/13450787436/job/37585901466#step:17:6536
The fix simply consists in creating the watchers *before* we start the
container but still *after* we create it -- this is non-blocking, and IIUC the
cgroup is guaranteed to already be present then.

As a follow-up for #10904, we do not need to set MEASURED_ROOTFS to no
on s390x explicitly. The GHA workflow already exports this variable.
This commit removes the redundant assignment.

This test verifies that, when ReadStreamRequest is blocked by the

On Ubuntu 24.04, due to the /usr merge, system-provided unit files
now reside in `/usr/lib/systemd/system/` instead of `/lib/systemd/system/`.
For example, the command below now returns a different path:
```
$ systemctl show containerd.service -p FragmentPath
/usr/lib/systemd/system/containerd.service
```
Previously, on Ubuntu 22.04 and earlier, it returned:
```
/lib/systemd/system/containerd.service
```
The current pattern `if [[ $unit_file == /lib* ]]` fails to match the new path.
To ensure compatibility across versions, we update the pattern to match both
`/lib` and `/usr/lib` like:
```
if [[ $unit_file =~ ^/(usr/)?lib/ ]]
```

Centralize all RustVMM crates to workspace.dependencies to prevent
having multiple versions of each RustVMM crate, which is error-prone and
inconsistent. With this setup, updates on RustVMM crates would be much
easier.

sudo hides the environment variables that are sometimes
useful with the builds (for example: proxy settings).
While install_oras.sh could run completely without sudo in
the container it's COPY'd to, make minimal changes to it
to keep it functional outside the container too while still
addressing the problem of 'sudo curl' not working with proxy
env variables.

Set CONFIG_BLK_DEV_WRITE_MOUNTED=y to restore previous kernel behaviour.
Kernel v6.8+ will by default block buffer writes to block devices mounted by filesystems.
This unfortunately is what we need to use mounted loop devices needed by some teams
to build OSIs and as an overlay backing store.
