Simplify NixOS-related commands
I use Makefile to simplify NixOS-related commands, which is very convenient. You can also use other similar tools to do this job, here I will only introduce my usage as a reference.
My Makefile looks like this:
makefile
#
# NOTE: Makefile's target name should not be the same as one of the file or directory in the current directory,
# otherwise the target will not be executed!

deploy:
nixos-rebuild switch --flake . --use-remote-sudo
debug:
nixos-rebuild switch --flake . --use-remote-sudo --show-trace --verbose
update:
nix flake update
history:
nix profile history --profile /nix/var/nix/profiles/system
gc:
# remove all generations older than 7 days
sudo nix profile wipe-history --profile /nix/var/nix/profiles/system --older-than 7d
# garbage collect all unused nix store entries
sudo nix store gc --debug

Save the above Makefile to the root directory of the flake, and then we can use make deploy to deploy the configuration to the local machine, and use make idols to deploy the configuration to all my remote servers.
