ran this this morning, about 8 hours after my last `guix package -u`:
efraim@debian-netbook:~/workspace/guix$ time ./pre-inst-env guix package -u && time ./pre-inst-env guix package -u && time ./pre-inst-env guix package -u

real	15m0.833s
user	5m53.268s
sys	1m26.056s

real	14m27.095s
user	5m50.848s
sys	1m25.156s

real	14m37.017s
user	5m55.564s
sys	1m30.536s

so I don't think the substitute info is the part that's slowing it down.
Conky shows me both guix hand guix-daemon working, so more likely something
else, like figuring out the substitutions.
