Regardless of the root cause of the problem, getting rid of the > trash directory before the next evaluation seems like a good idea. Yeah I don=E2=80=99t know what happened to the GC process but it disappeared earlier today. Then I started things like this: unshare -m sh -c 'mount --bind -o remount,rw /gnu/store; rm -rf --one-fil= e-system /gnu/store/trash/[abc]*' which is equally slow (perhaps slightly slower: it seems to do more syscalls per file to remove than the guix-daemon code). Anyway, I=E2=80=99ll let it run hoping it=E2=80=99ll be done by the next GC. Ludo=E2=80=99.
