bug#61627: Cannot start a container built with `guix system container --network'.

[Nicolò Balzarotti]

Hi, 
I'm on eb87d2c4 (just updated a 412(!) days old guix server O.o) and
I can confirm this is still happening

(btw, this is the only problem I had in upgrading, so great job guix)

Thanks!
Nicolò
