Re: Guix home, guix system, channels, some noob questions

[Julien Lepiller]

guix install something installs for the current user. Note that, if you do that 
as root, the package is also only available to root. The only way to install or 
remove a global package is through guix system and its configuration file.

I don't know how guix home interacts with other solutions.

We don't have a good solution for secrets. We advise to manage the 
"out-of-band" to make sure that you don't share the secret accidentally (eg. 
publishing your configuration with others) and that the secret doesn't end up 
in the store (it's world-readable).
