Running: guixSD.
Scenario: Finding and installing doc for a package (ncurses) used by aby a global package (emacs) I hit the following error.
FWIW, IMHO, this functionality, and the ease with which it is available,is truly awesome!
This failed for both user and root.
Common steps============emacs 'M-x guix-system-generations'
In *Guix Generation List: system* move to current & RET
In *Guix Package List: profile* move to emacs & RET
In *Guix Package Info: profile* for emacs-24.5 I move to 'ncurses-6.0' & RET
In *Guix Package Info: profile* for 'ncurses-6.0' move to doc Install & RET

A-a-a! What you tried is more or less the equivalent of:
guix package -i foo --profile=/run/current-system/profile
A system is "composed" during "guix system" command, and it isimmutable, so you can't install packages to an existing system.
The only proper way to install packages globally is by adding them toyour system config.scm and running "guix system reconfigure".
You shouldn't (!) try to install packages in a system profile in anyother way.

Thanks God /gnu/store on GuixSD is read-only even for root!
A system is not just a set of packages. Look at any"/var/guix/profiles/system-XX-link" file. It is a symlink to the store."profile" (which contains the installed packages) is only one of itssubdirectories. What you tried led to an attempt of making a newgeneration of this "profile" directory, and happily in failed even forroot.
Why do you install everything globally? IMO it is much more convenientto manage a user profile (no root involved, no "system reconfigure" allthe time).
Really, it is a big feature of Guix to be able to install packageswithout using root rights. Of course it's your choice, but I highlyrecommend to install your packages in ~/.guix-profile. The only globalpackages I added to %base-packages are: 'nss-certs' and 'iproute'.

No, I was not trying to do that. I expected your _doc_ button to do ...
guix package -i <ncurses-6.0 doc>.
That is supported, isn't it?

Not brave. As I understand your doc, the root user can install packagesin a root profile. So, I expected your _doc_ button to do ...
guix package -i <ncurses-6.0 doc>
... for root. That is supported, isn't it it?
I only tried it on root because I thought not work for uer was a gut. Iexpected it to work for root.

Well, let me count the reasons...
1) because that is the first thing you showed me how to do as I wasinstalling from USB
2) because that is what people who own and/or administer servers needand/or expect to do
3) because this is how the Debian 8 servers that I want to convert toguixSD are configured, and I want to see, as a start, a replication ofthat situation
4) Because I have multiple accounts for various things that need toshare a base set of packages
5) Because you can't call guixSD a real distribution if it doesn'tsupport this mode of use
6) Because I am trying to help you test guixSD
7) Because if guixSD does not support this well I can't pitch a trialdeployment at my workplace
But, no, NOT because I am trying to make you CRAZY.
Also, just to be clear, I was not trying to install the curses.6 docglobally. I was trying to install it locally as 1) user, and when thatfailed as 2) root.
Toggle quote (4 lines)> IMO it is much more convenient> to manage a user profile (no root involved, no "system reconfigure" all> the time).
Yes and I was trying to use that guix feature to to add doc for apackage to my user profile.

I understand why guix developers and packagers run this way and Iunderstand the attraction. I have other use cases where this approachmore closely apply. However, if you want to get other people that arenot guix developers or packagers to adopt guix and guixSD, you need tosupport users are not so agile, or just want to user guixSD as adistrubtion.
Recap: these are both bugs not operator error.

Sorry for the confusion, but this was a wrong expectation. When youpressed "Install" button, you got a message:
Toggle snippet (6 lines)Profile: /var/guix/profiles/system-XX-link/profile
Package(s) to install: ncurses-6.0:doc (gnu/packages/ncurses.scm:90:4)
And you confirmed, that you wanted to install it in/var/guix/profiles/system-XX-link/profile :-)
Toggle quote (2 lines)> That is supported, isn't it?
It is. For example, you can "M-x guix-packages-by-name RET ncurses"(package names are completed) and install it the way you tried. Or froma list of packages (for example, after "M-x guix-search-by-name RETguile"), you can mark several packages for installing with "i" andexecute the operation with "x".
Operations on packages (installing/upgrading/deleting) in these"List"/"Info" buffers are performed using a profile which is the currentfor these buffers. Moreover the buffers are named like this:
*Guix Package Info: guix-profile*
"guix-profile" here is the last part of the profile file name:"/var/guix/profiles/per-user/<user>/guix-profile".
(We can change a default buffer name to contain a full profile name, butit will be too long, I think)
Anyway, when you looked at the "global" packages, a system profile wasused (as this is where global packages are installed), and when youtried to install "doc" output of ncurses, it was tried to be installedin the system profile which is impossible.

If by root you mean globally (i.e., to a system profile), then no. Theonly way to install packages globally is by adding them to a systemconfig and running "guix system reconfigure".
If you mean to install packages into a root's profile (which is probably/root/.guix-profile), then yes: in the same way as you would do for anon-root user.

But please pay attention to messages, confirmations, errors. You weretold that you were trying to install to a system profile, not to aroot's user profile.

It is supported through "guix system reconfigure". There is no other way.

Thanks :-) OK, you are free to do it the way you like. I was justsaying that managing users profile is more convenient IMO.

Now I understand your intention, but in fact you tried to install it toa system profile both times.
After all I see why you were confused. Emacs interface has always beenaimed only for a user profile. "M-x guix-system-generations" was addedvery recently just to show what systems you have and what globalpackages they contain, and by accident you can perform the same actions onthese system packages as with user profile.
I'm going to remove this false possibility (I mean, a user shouldn't geta chance to install anything to a system profile) to avoid futureconfusions. Thanks for reporting!

Hi!
As a side note, I think it would be very helpful if you could spend moretime to make your messages concise and to-the-point. I understand it’snot always easy, but it would increase throughput and probably reducefrustration as well! :-)
That said, thanks for your reports, which have already helped us improvethe system in several ways.

To be clear, I am not the least frustrated. But I may haveover-dramatized hypothetical frustration in hypothetical users ;)
