Describe the problem

Initial state of resolv.conf:
search lab lan

When netbird client connects, it does insert .netbird.selhosted as a search domain:
search lab netbird.selfhosted lan

The problem is that the VPN resolution matches before the local DHCP provided suffix.
I did not see a way to configure the order of insertion.

On another machine which has only:
search lan

after connection I got:
search lan netbird.selfhosted

To Reproduce

Simply connect to netbird.

Expected behavior

In resolv.conf, netbird suffix should be added last:
search lab lan netbird.selfhosted

Are you using NetBird Cloud?

Self-hosted Netbird

NetBird version

0.41.3
netbird version

Is any other VPN software installed?

No

Debug output

[turn:netbird.anon-tDP76.domain:3478?transport=udp] is Available
Nameservers:
FQDN: stumpy.netbird.selfhosted
NetBird IP: 100.72.161.84/16
Interface type: Kernel
Quantum resistance: false
Networks: -
Forwarding rules: 0
Peers count: 5/6 Connected

Have you tried these troubleshooting steps?

[X ] 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
