Up to the resolv.conf, that is exactly what I do. But that change to 
resolv.conf adding the search line has been required since red hat 5.0 
in 1998. until bullseye. Just last week I found it is not needed in an 
armbian bullseye install.

Now, if I could figure out why printers, shared om this bullseye machine 
work perfectly when accessed by a buster machine, but cannot be seen by 
any other bullseye machine here, debian or armbian. My logs show an auth 
failure but all are DefaultAthorization Basic. And turning on debugging 
doesn't tell me anything more useful. Like why... I've managed to get 1 
armbian machine trying to connect, but my logs are huge cuz it tries 
every 11 seconds

Take care & sty well, Greg
