[root at localhost ~]# lsb_release -d Description: CentOS Linux release 8.2.2004 (Core) [root at localhost ~]# cat /etc/resolv.conf # Generated by NetworkManager search subdomain.company.com company.com nameserver 1.2.3.4 nameserver 5.6.7.8 [root at localhost ~]# host foo foo.subdomain.company.com has address 1.2.3.4 [root at localhost ~]# host foo.subdomain Host foo.subdomain not found: 3(NXDOMAIN) [root at localhost ~]# host foo.subdomain.company.com foo.subdomain.company.com has address 1.2.3.4 [root at localhost ~]# The expected result is that the lookup for foo.subdomain works, like it does under CentOS < 8. I tested this also on a RHEL8 machine and followed https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/8/html/configuring_and_managing_networking/manually-configuring-the-etc-resolv-conf-file_configuring-and-managing-networking to disable DNS processing by NM, but this did not change the outcome. How can the pre-CentOS 8 behaviour be restored?
