In recent days, I reconfigured my system in the same way that I always do it.
The resulting system was malformed, preventing boot and the use of `guix system`. Specifically, the files that make up the system itself --- such as '/var/guix/profiles/system-NNN-link/parameters' --- are empty! Zero bytes. IIRC, I was able to work around it by running the activation scripts from an older generation "by hand", but I don't remember for sure if this was sufficient or not. For example: `guile -s /var/guix/profiles/system-NNN-link/activate` I didn't report this to bug-guix (although I did complain on #guix), because I thought it was just me, but now another user on #guix has the same problem: https://logs.guix.gnu.org/guix/2025-03-11.log#205907 `guix gc --verify=contents` reported all the broken files. Repair was not possible for most of them. `btrfs scrub` was successful, and memtest86+ passed 9 times, so I'm relatively confident in the filesystem and the hardware. I don't have a handle on the relevant details, but here is some system information: ------ # cat /etc/fstab # This file was generated from your Guix configuration.
