Hi we have recently upgraded from 7.9.3 to 7.17.1. We now get this error in the Metricbeat logs

```auto
2022-03-24T19:02:27.030Z ERROR module/wrapper.go:259 Error fetching data for metricset system.filesystem: error getting filesystem list: open /etc/mtab: no such file or directory

```

Our /etc/mtab is a sym link

```auto
ll /etc/mtab
lrwxrwxrwx. 1 root root 17 Jan 31 15:24 /etc/mtab -> /proc/self/mounts

```

Anyone knows how to fix this? I have already tried using `filesystem.ignore_types: [] ` and it removed these logs but still getting the /etc/mtab error

```auto
2022-03-24T18:23:25.615Z INFO filesystem/filesystem.go:58 Ignoring filesystem types: sysfs, tmpfs, bdev, proc, cgroup, cgroup2, cpuset, devtmpfs, configfs, debugfs, tracefs, securityfs, sockfs, bpf, pipefs, ramfs, hugetlbfs, devpts, autofs, mqueue, pstore, rpc_pipefs, overlay, nfsd, binfmt_misc

```

We also see this error in the Kibana Discovery panel.

After more investigation this appears to be an upstream issue.

> <https://github.com/elastic/beats/issues/30590>
>
> \- Version: 8.0
> 
> Metricbeats system module expects the \`/etc/mtab\` symlink to \`…/proc/mounts\` be present for example for the fsstat metricset. When running in a containerised environment this symlink is not present on all container runtimes. For example \`containerd\` and \`cri-o\` do not create this symlink.

> We noticed this because ECK e2e tests started failing. https://github.com/elastic/cloud-on-k8s/issues/5345#issuecomment-1049024021 is the related issue where we track and analysed the build failures.

Anyone can suggest a work around?

/etc/mtab is not linked in 7.17.1  
ls -rtl /etc/mtab  
ls: cannot access '/etc/mtab': No such file or directory
