Is this some declarative joke I am too imperative to understand?
Info:
nixos-rebuild switch
= build the new system configuration (from/etc/nixos/configuration.nix
or flakes) and activate it immediately without reboot.- It builds the new system in
/nix/store
. - Updates the GRUB/systemd-boot entries.
- Switches to the new configuration right away (systemd units, services, kernel params if possible, etc.).
- Leaves the old generations available for rollback (
nixos-rebuild switch --rollback
).
So: “switch” means build + activate now
I never use nixos, but I just got intrusive thought to make that command get invoked automatically every time the config file is modified.
My most intrusive Linux thought is to symlink
vi
toemacs
(or vice versa).I will find you, and I will break your fingers.
