Chart Configuration

nothing special. I enabled ingress/traefik with certificate. This is working. no problem here.

Describe the bug

In the GUI of uptime kuma you can enable nscd (a service to cache DNS requests). I noticed that requests are not cached because I see too many requests on my nameserver (AdGuard Home).

In the pod I see that there is a problem with nscd. First the log shows that nscd did not start. When I start it manually it also fails due to a permission problem. See screenshots attached.

To Reproduce

1. On you user profile in uptime-kuma select "Settings"
2. Ensure that you have the option: "Enable NSCD (Name Service Cache Daemon) for caching all DNS requests" enabled
3. Log into the pod and try to rund nscd -g to get some statistics from the daemon. -> this will fail as the daemon is not starting.
4. When you start the daemon manually with "nscd --debug" you see that it cannot start due to a permission problem:
   it cannot create the /var/cache/nscd/hosts as it is a read-only file system.
   (This is probably the root cause).

Expected Behavior

When you enable NSCD in the GUI then you expect that this daemon starts and caches some of the DNS requests.
