bug#52667: System reconfiguration fails to build linux-modules.drv

[Vivien Kraus]

Dear guix,

On master, I can’t reconfigure my system, because the linux-modules.drv
fails with the following error:

Backtrace:

The top of the backtrace is this file,

module out-module) (maybe-uncompress out-module))) (delete-duplicates
modules)) (write-module-name-database ((@ (guile) getenv) "out")))

This is the linux-related part of my system configuration:

(operating-system
  (kernel linux-libre-lts)
  (kernel-arguments
   `(,@%default-kernel-arguments
     "modprobe.blacklist=amdgpu,radeon"))
  …)

Best regards,
