list of available updates for globally installed packages

list of available updates for globally installed packages

[Reza Alizadeh Majd]

Hi Guix, 

I asked before about a way to check if any update is available for
_Globally Installed Packages_ in `/run/current-system/profile` in this thread: 

https://lists.gnu.org/archive/html/help-guix/2019-10/msg00167.html

as suggested in above thread, I was pointing the target profile to achieve desired results: 

```
guix package -p /run/current-system/profile -n -u
```

but recently after updating the guix, I receive following error when I run above command. it seems that there is a permission issue occurs when guix tries to access to the system profile. 

```
panther@panther ~$ guix package -p /run/current-system/profile -n -u
Backtrace:

```

could anyone help me on this, or alternatively suggest a working solution to check for list of available updates for packages that globally installed using `guix system reconfigure` ?
