We should avoid using it up unnecessarily. [Test cases] == netplan == 1) Boot system with netplan config; using networkd renderer 2) Validate that it starts and does not cause undue delay. 2b) strace nplan at boottime (the netplan generator at /lib/systemd/system-generators/netplan) and validate it does not call get_random() / uuid_generate(). 3) Validate that config with NetworkManager renderer generates UUIDs. [Regression potential] Netplan depends on UUID generation to create correct networkManager configuration for VLANs. This is a specific use-case that is typically not hit, but any failure to generate valid NetworkManager configuration would be a regression from this SRU. --- enabling networkd appears to eat up entropy as seen in openssh autopkgtest failing, when networkd is enabled by default.
