The daemon reserves a bit of extra space before starting operation (see =E2=80=98reserve-space?=E2=80=99 in (guix store)), which should be enough t= o gracefully handle situations where builds are filling the disk. However, there can also be non-Guix processes filling the disk, to the point where it=E2=80=99s completely full, and at that point sqlite3 (which = the daemon uses) may be unable to operate. I=E2=80=99m afraid there=E2=80=99s little we can do in this case. Thoughts? Ludo=E2=80=99.
