That did the trick, thank you.
I added urandom-seed to the services for this system, but reconfigure failed because I use the desktop-services as a base, which includes urandom-seed as a service from base-services.
The reconfigure and reboot did not hang this time, though.
Everything else I use looks good, thanks!
