Original GitHub issue: https://github.com/netbirdio/netbird/issues/5354

Describe the problem

Running docker.io/netbirdio/netbird in read-only mode yields the following warning whenever netbird gets executed:

client/internal/profilemanager/profilemanager.go:92: failed to get config directory: mkdir /root/.config: read-only file system

This doesn't stop the client from working. However, running netbird status --json, for example, doesn't produce a valid JSON file because of the warning.

To Reproduce

podman run --rm -it --read-only -v dummy:/var/lib/netbird --tmpfs /var/log/netbird docker.io/netbirdio/netbird:0.65.1
Let it initialize
Ctrl-C
podman run --rm -it --read-only -v dummy:/var/lib/netbird --tmpfs /var/log/netbird docker.io/netbirdio/netbird:0.65.1
Observe cited warning after some seconds

Expected behavior

netbird shouldn't display a warning about a directory it can't create if it doesn't need to create a file inside it.

If the folder is important, it should be created when building the image.

NetBird version

0.65.1

Have you tried these troubleshooting steps?

Reviewed client troubleshooting (if applicable)
Checked for newer NetBird versions
Searched for similar issues on GitHub (including closed ones)
Restarted the NetBird client
Disabled other VPN software
Checked firewall settings
