    Dependency to isc-dhcp-client for kernel package

    Hi, apparently the package "proxmox-kernel-6.17" was the last one to not have a dependency to isc-dhcp-client. As ISC DHCP Client is EOL since 2022, we have replaced it with udhcpc and Puppet takes care that isc-dhcp-client is purged. Therefore, "apt autoremove" removes newer kernels. Why is...
