How to fix "same boot loader version in place already"?

Help

Hi, I’ve noticed that when I’m rebuilding my system, I get something like this (has been happening for about a month or so):

$ sudo nixos-rebuild switch --flake ~/dotfiles/.config/nixos-config/#$(hostname)

building the system configuration...
Checking switch inhibitors... done
Skipping "/boot/EFI/systemd/systemd-bootx64.efi", same boot loader version in place already.
Skipping "/boot/EFI/BOOT/BOOTX64.EFI", same boot loader version in place already.
activating the configuration...
setting up /etc...
reloading user units for bs...
restarting the following user units: nixos-activation.service
restarting sysinit-reactivation.target
the following new units were started: fwupd-refresh.service, fwupd.service, network-online.target, NetworkManager-dispatcher.service, NetworkManager-wait-online.service
Done. The new configuration is /nix/store/bxsbxy7ga1q68p3dh4m7c55n51af28bs-nixos-system-nixos-main-26.11.20260715.753cc8a

What is concerning me is these two lines:

Skipping "/boot/EFI/systemd/systemd-bootx64.efi", same boot loader version in place already.
Skipping "/boot/EFI/BOOT/BOOTX64.EFI", same boot loader version in place already.
activating the configuration...

The rebuild is done properly, but is there anything else I should do?
I read in this forum that maybe nixos-rebuild switch --install-bootloader would fix it, but haven’t tried it, as I didn’t find much info about what it actually does. Any ideas?

There is nothing to act. It is just informing you, that the bootloader is recent and therefore won’t be replaced.

Yea, maybe we should suppress this output. It’s new because of an improvement that was made to the boot loader module, and this output is a side effect. It’s harmless but it’s also just unnecessary noise for most users.
