I noticed that if you call "guix COMMAND" for some C=
OMMANDs without any
options given, they produce something which is not v=
ery useful to the
user=2E I first noticed it with guix pack:

When=
 "guix pack" is run without any options, it builds an empty pack:

$ =
guix pack

fest

I think from a user perspective it would be better to print a h=
elp
message and not build an empty pack=2E

On the other hand, I t=
ried out other guix commands and at least it is a
consistent behaviour, =
they start with the default values, like "guix
graph" outputs just an em=
pty graph=2E

"guix system" complains it needs a subcommand, which is=
 a different
case=2E

But then again we have this complaint:
guix system container
guix system: error: wrong number of arguments fo=
r action 'container'

WDYT?

I think we should print helpful hints or the content= s of --help in these situations=2E
