I am not sure that I get it. Per your reproducer you explicitly specify _prepend_ in the config file and then complain that the domain gets _prepended_ ? |

_prepend domain-search "abc.com"_ in the step 1 in reproducer should be _append domain-search "abc.com"_. |

I cannot reproduce your exact issue but there indeed seems to exist a problem with dhclient. On my system (which is a fully updated 7.9) if I use any of the prepend or append options, the search domain sent by the DHCP server is ignored and replaced by the values provided by prepend and append from dhclient's config file, postfixed with a dot ( "abc.com." for instance ) my test was performed by creating the adequate dhclient.conf file and then issuing ifdown enp2s0; rm /etc/resolv.conf; ifup enp2s0; cat /etc/resolv.conf Unless someone chimes in with a correction or better idea, I suggest to file a bug at bugzilla.redhat.com and hope for the best ( RHEL 7 is in maintenance mode so RH no longer provides anything but fixes they consider to be of high importance, mostly high-impact security fixes ). CentOS is built from the sources provided by RH so if they provide a fix, CentOS will inherit it automatically. |
