I tried system.build.installBootLoader = “${pkgs.coreutils}/bin/true”;
but no luck

Here’s a relevant line from the logs you provided:

 efiSysMountPoint = ‘/boot’ is not a mounted partition. Is the path configured correctly?

It says that your /boot isn’t mounted [correctly].

ok so I have to mount it? The system is read-only

4

What do you mean by “the system is read-only?” It shouldn’t be.

6

/nix/store is read-only yes, there’s no reason to touch anything there. What @thefossguy said was to mount whatever EFI system partition (ESP) under /boot

Or you must change your configuration to point at wherever your ESP is actually located at.

About /nix/store Is there a way to edit a package conf file on nix without learning entire nix language? Few packages use conf files say nano.conf and if you want to edit, well, I assume you need to paste that to configuration.nix or compile it yourself.

About ESP. Is it normal that I can boot and type from my machine tho the /boot not mounted.

I managed to mount /nix/store with /boot partition

building Nix…
building the system configuration…
File system “/boot” is not a FAT EFI System Partition (ESP) file system.
systemd-boot not installed in ESP.
No default/fallback boot loader installed in ESP.
