[Pdns-users] powerdns recursor 5.1 doesn't support non-yaml syntax?

Re-reply for list.

Well...

5.0.x had existing default old-style recursor.conf (default values, no 
modifications done). After upgrade this file was rewritten to new 
recursor.conf with yaml syntax (so all default values are gone).

tldr; this is upgrade 5.0.8 -> 5.1.1 (alltime pdns repository), not the 
new install.

Renaming recursor-local.conf to recursor-local.yml:
###recursor-local.yml

For me, upgrade 5.0.8 -> 5.1.1 breaks because it overwrite even default 
old-style recursor.conf and all shit with mix yaml/old-style happens.
