I wrote a rebuild script which opens my config in nvim, checks for changes, and rebuilds if changes were made.
When I run the script on my desktop everything is fine, but when I run it from my laptop (nix-darwin if that matters), I get error: opening lock file '/nix/var/nix/profiles/system.lock': Permission denied. The weird thing is that I can rebuild manually, it’s just when it’s running in this script.
set -e
red=$(tput setaf 1)
reset_color=$(tput setaf 9)
force=false
git_push=false
notify=true
reset() {
popd >/dev/null
exit "$1"
}
show_help() {
cat <<-EOF
dot: a command to rebuild configs
flags:
-f force rebuild even when there weren't changes
-h help
-N disable notificaitons
-p run git pull before editing config
-P git push after config is done

I have two computers so I made a nix wrapper around this script and pass the correct commands as environment variables. I’ve tried having the rebuild command be the standard darwin-rebuild as well as using nh.
my full config is here in case you think it might be something else. I appreciate any help with this, it’s incredibly inconvenient.
