Hi,

‘guix substitute’ displays nothing when it connects to substitute
servers. Thus, if the connection attempt stalls, ‘guix’ commands just
print nothing.

Here’s what ‘guix build’ sees when ‘guix substitute’ is busy trying to
connect to a server:

Toggle snippet (7 lines)
11:31:00 read(13, "gmlo\0\0\0\0", 8) = 8 <0.260108>
11:31:00 read(13, "\r\0\0\0\0\0\0\0", 8) = 8 <0.000017>
11:31:00 read(13, "substitute: \r\0\0\0", 16) = 16 <0.000018>
11:31:00 read(13, 0x40cddd0, 8) = ? ERESTARTSYS (To be restarted if SA_RESTART is set) <3.681580>
11:31:04 --- SIGINT {si_signo=SIGINT, si_code=SI_KERNEL} ---

We should arrange so that ‘guix substitute’ prints an initial message
instead of just clearing the line so that users have an idea of what’s
going on.
