darwin-rebuild don't auto switch/link to current system

[nicehiro]

Hi, thanks for your great work!

I'm a newbe to use nix on macOS. After a system upgrade, the nix won't automatically switch current-system to the new one. I have to link and activate the build system by:

cd run/
sudo ln -s new-built/system/ current-system
cd current-system
sudo ./activate

After this, the command nix run .#build-switch won't update the system and only generate result. The log is attached here:

I assume that the darwin-rebuild process is not finished. But I don't know how to fix it.

Please let me know if you need any information. Thanks for your help.
