Ah, I hadn=E2=80=99t thought about it.

Hmm opening a connection to the daemon doesn=E2=80=99t cost much, but OTOH =
it=E2=80=99s
best if we can avoid it here since =E2=80=98guix time-machine=E2=80=99 is j=
ust a
trampoline.

Dunno, I=E2=80=99ll comment on the new patches and we=E2=80=99ll see.  :-)
