Rebuild the system configuration but not switch:

Environment="<ENV_VAR_NAME>=<ENV_VAR_VALUE>"
EOF
systemctl daemon-reload
systemctl restart nix-daemon

Clean the machine:

sudo nh clean all

This nixos config is designed to build remote nixos system on a local machine and push it to the remote machine, use with ssh config:

# Note that it required no sudo permission on the local machine
nixos-rebuild --target-host "<remote-host>" --sudo switch --flake ."#<remote-host>" |& nom

With the ssh config like:

Host <remote-host>
  User <username>
  Hostname <ip-address/domain>

Emergency rollback to the previous boot entry (for grub):

sudo grub-reboot '1>1'
sudo reboot
