Today I noticed that the DHCP client installed by default seems to be dhclient from ISC-DHCP. This is problematic as this DHCP implementation has reached its end-of-life in 2022 [1]. This is also mentioned in the Guix package description. The dhcp-client-service-type has a package configuration option, in theory, allowing usage with other DHCP clients. Unfortunately, it seems to require that the package provides /sbin/dhclient and I am not aware of any package that has this executable. In general, it seems there is no other DHCP client package available in Guix. Therefore, I believe the course of action here would be to: (a) package a different DHCP client (dhcpcd [2] may be a good candidate) and (b) make sure that dhcp-client-service-type is compatible with this client and uses it by default. I would argue that this is an important issue, as a DHCP client processes untrusted input from the local network and is thus subject to potential security vulnerabilities.
