Hi, I’ve been having issues with the filesystem that holds /gnu/store recently, causing corrupted/broken files. When trying to repair these broken files with `guix gc --verify=repair,contents` it properly detects that store items’ hashes do not match the ones recorded in the database and redownloads/rebuilds them. However, the corrupted store items are never actually repaired – not by `guix gc` and not by `guix build --repair`. Attached is a testcase showing that deduplication is the problem, because repairing will just hardlink the (broken) deduplicated file instead of replacing it with the downloaded/built file. I tried the daemon’s `--disable-deduplication` too with same results. Cheers, Lars
