Linux Core Component systemd Receives v259 Update: Enhanced DHCP Functionality

The systemd v259 version has been released, with this update primarily enhancing the functionality of systemd-networkd. The new version implements a resolve hook feature for the internal DHCP server, enabling hostnames tracked in DHCP leases to be resolved locally. This feature is enabled by default and applies to DHCP servers running on local hosts within systemd-nspawn or systemd-vmspawn networks. As a critical component of Linux systems, each systemd update impacts the entire Linux ecosystem’s operation, and this improvement will enhance the convenience and efficiency of network configuration.
