DNS forwarding throwing error

Thanks for your support @Dmitry, yet, there error is still there

[ service dhcp-server ]
Traceback (most recent call last):
File “/usr/libexec/vyos/conf_mode/dhcp_server.py”, line 822, in
apply©
File “/usr/libexec/vyos/conf_mode/dhcp_server.py”, line 811, in apply
os.mknod(lease_file)
FileNotFoundError: [Errno 2] No such file or directory

However, when I edit the path in /usr/libexec/vyos/conf_mode/dhcp_server.py to:

/opt/vyatta/config/dhcpd.leases

The scritps runs smoothly to it’s end without throwing an error. I found the description how to tackle the situation here: https://forum.vyos.io/t/dhcp-service-mknod-error/3392

Sadly, the newly applied and saved config does not survive the reboot. Do I have to explicitly select a new bootable vyos squashfs.img on boot?
