   host -N2 foo.subdomain

work on CentOS 8?  Does it work if you put ndots: 2 in resolv.conf?

There may have been a change in behaviour - from the tests I've done it
seems more like it's fixing a bug/inconsistency somewhere because doing
   host -N1 foo.subdomain 

should not work, but it does on CentOS 7.
