Hi Guix,

Today after a guix pull to commit 
e3545ffcf95bffbbd967efd852715f4f0a9be290, guix system reconfigure fails to 
install grub (bios grub on x86_64) with

guix system: error: failed to install bootloader /gnu/store/45myfaqas69fnp3mfbqlsf9lafm30cl0-bootloader-installer

Unfortunately, I don't remember the last commit for which I successfully 
reconfigured and installed gurb. My operating system definition is below.

Best,

I can replicate this bug, however it is still successfully installing a
new system configuration. The error printout seems erroneous (pun
intended).

I am sure there is a regression somewhere, but it does not seem to
adversely effect the method in question.

Indeed, I also do get a new system configuration reflecting my changes. 
However, I'm not sure if the output is just erroneous of if grub is really 
failing to be installed. By that I mean that the grub-install call is 
failing, resulting in this output. Since grub has been previously 
installed to my disk, most of the time I don't need to install the 
bootloader binary again, so this failure doesn't cause problems.

I wonder if Ludovic's recent work [0][1] on handeling the bootloader 
messages could be the cause.

What was printed before that?  Any hints?

It could be related to the changes I recently made, indeed.

Thanks,
Ludo’.

Fixed in 8ffab257ddb6c5df1ac43b9baeb5f0373bffb482.

As you found out, ‘grub-install’ was actually successful but there was
an unbound variable error while displaying the success message…

Thanks,
Ludo’.
