Hi Ludo!

Sorry for replying just now. I did not try to reproduce the bug back at
that time. So, I took the time yesterday to try to reproduce the bug. And,
I cannot reproduce the problem after repeating the following rough steps
two times with the same bootable disk and machine and network (but the
external connection to the ISP may have changed in the mean time):

1. Format my /dev/sda8
2. Swapon my /dev/sda7
3. mount my /dev/sda8 to /mnt
4. herd start cow-store /mnt
5. umount /tmp
6. mount --bind /mnt/tmp2 /tmp
7. ifconfig, wpa_supplicant, dhclient
8. guix pull
9. guix system --no-grub --keep-failed init /mnt/etc/config.scm /mnt

The whole process took just about 100 minutes.

So, I cannot reproduce the bug.

Thanks.
