It&#8217;s improbable; NetworkManager switched to its own DHCP client by default starting with the v1.20 release in 2019.<\/p>\n<p>Recent updates in <em>NetworkManager<\/em> 1.50 include:<\/p>\n<ul>\n<li><strong>Introduction of a new timeout option for checking connectivity<\/strong><\/li>\n<li><strong>Support for configuring virtual ethernet (veth) interfaces in <\/strong><code>nmtui<\/code> <strong>has been added<\/strong><\/li>\n<li><strong>Support for multiple gateways within a single network in ndisc<\/strong><\/li>\n<li><strong>Configuration options for channel-width in AP mode for Wi-Fi connections<\/strong><\/li>\n<li><strong>Capability to reapply VLANs of a bridge port<\/strong><\/li>\n<li><strong>Retrying hostname resolution if it encounters failure<\/strong><\/li>\n<li><strong>Reverting to utilizing sysctl ipv6.conf.default for ip6-privacy<\/strong><\/li>\n<li><strong>Elimination of offensive terms from keyfiles<\/strong><\/li>\n<\/ul>\n<p>The last point is part of Red Hat&#8217;s <a href=\"https:\/\/issues.redhat.com\/browse\/RHEL-52597\" target=\"_blank\" rel=\"nofollow noopener\">\u2018conscious language initiative\u2019<\/a>. <em>NetworkManager<\/em> has already ceased using \u201coffensive terms\u201d (it can still read them if they exist) and this release finalizes the effort by preventing such language from being newly written into keyfiles.<\/p>\n<\/p>\n<p><p>At last, with the release of <em>NetworkManager<\/em> 1.50, the system hostname is now determined by performing a reverse DNS lookup on the addresses defined in the interfaces, taking into account the contents of \/etc\/hosts.
