Perhaps “(typically @file{/etc/config.scm})” should go next to
“@var{file} must be …”?

But if the person doesn’t read more than a few lines of the page, it
won’t help.

I was thinking we could have “guix system reconfigure” without arguments
pick up /run/current-system/configuration.scm.  Perhaps that’d help?

Thanks,
