This directory serves as a database for deduplication, which is the process of using hard links to make sure each individual file in /gnu/store is stored only once in the file system. If you =E2=80=9Crm -rf=E2=80=9D this directory, things will keep working, b= ut that will hamper deduplication going forward. You can force a store-wide deduplication pass, though, by running =E2=80=9Cguix gc --optimize=E2=80=9D. HTH! Ludo=E2=80=99.
