I figured out what was causing the issue and it's not a bug.

I had to disable the guix-defaults for the home-bash-configuration as explained here https://issues.guix.gnu.org/67652 since they were already declared within a local file.

Hello everyone,
lately, I've been experiencing a weird behavior when reconfiguring my system.

The command hangs indefinitely after displaying "guix system: bootloader successfully installed on /(dev/sda)" and I have to hit C-c to get back to the prompt.

I think there is nothing wrong with my config, which is the following:

```
;; System config

Could this be a bug or am I missing something?

Thank you
