Refresh /etc/resolv.conf automatically

Earlier today, I changed the DHCP settings in my router because I have a new local DNS server.
I have set the lease time in my router to 10 minutes.
I would have expected that this change was propagated through my netwerk, but the proxmox host did not pick it up, apparently.
/etc/resolv.cont still has the ip address of the old DNS server, which does not exist anymore.

It is not difficult to fix, but how could I have avoided this?

For my Proxmox server I had to specifiy it manually:

is your PVE taking its IP address also from DHCP? if not then the DHCP option won't do much..

I am quite sure it does, but I will double check. Thx.
