However, this does not imply that *all* the actions modifying from one state to another must also be triggered in unpredictable moment. For instance, I choose when I wash family=E2=80=99s clothes and the wash-ma= chine does not start by itself when the unpredictable stack of family=E2=80=99s d= irty clothes is enough. Because, maybe today it=E2=80=99s rainy so drying is difficult and tomorrow will be sunny so it will be a better moment. :-) For me, =E2=80=9Cguix gc=E2=80=9D should be the driver for cleaning all the= various Guix caches. Anyway. :-D
