The ‘static-networking’ service can remain in ‘starting’ state forever
when it specifies a nonexistent NIC.
This can be reproduced by running a system such as hydra/bayfront.scm
(in maintenance.git) in ‘guix system vm’: shepherd will wait for
‘networking’ to start forever, preventing the machine from being cleanly
halted.
I believe this is due to indefinite blocking in ‘network-set-up/linux’:
;; Before going any further, wait for the
;; device to show up.
(wait-for-link
#$(network-address-device address)
#:blocking? #f)
It should instead wait for a limited amount of time (info "(shepherd)
Defining Services").
