Install image with custom services

[Jack Hill]

Hello Guix,

I'm trying to create an installation image that uses Network Manager to 
configure networking (For use at a site with WPA-Enterprise networks). I 
came up with the following:


```scheme
(define-module (jackhill system install)
  #:use-module ((gnu packages gnome) #:select (network-manager) #:prefix 
package:)
  #:use-module (gnu services)
  #:use-module (gnu services networking)
  #:use-module (gnu system)
  #:use-module (gnu system install)
  #:use-module (srfi srfi-1)
  #:export (my-installation-os))

(define my-installation-os
  (operating-system
(inherit installation-os)
(packages (cons package:network-manager
 (operating-system-packages installation-os)))
(services (cons (service network-manager-service-type)
(remove (lambda (service)
  (eq? (service-kind service) connman-service-type))
(operating-system-services installation-os))

my-installation-os
```

However, passing that to guix system disk-image results in:

```
guix system: error: more than one target service of type 'shepherd-root'
```

Thinking that I had done something wrong with removing the connman-service 
and adding the network-manager-service, I created a more minimal operating 
system definition:


```scheme
(define my-installation-os
  (operating-system
(inherit installation-os)
(packages (cons package:network-manager
 (operating-system-packages installation-os)))
(services (operating-system-services installation-os
```

To my surprise, this also fails with

```
guix system: error: more than one target service of type 'account'
```

However,

```scheme
(define my-installation-os
  (operating-system
(inherit installation-os)
(packages (cons package:network-manager
 (operating-system-packages installation-os)
```

sucseeds.

Should these last two operating system definitions not be equivalent? 
What's going on here?


Thanks,
Jack

I confirm the problem is solved.  A few minutes ago I have invoked
~guix pull~ and then I was able to build Gnucash.  Then I fired up
Gnucash and it showed its welcome dialog.

Thank you!

Sorry, the lines were not copied consistently.  Now the whole
encryption/decryption process verbatimly copied from my terminal:

$ date > test.txt
$ gpg --output test.txt.gpg --encrypt --recipient ma...@hulten.org test.txt
$ gpg --decrypt test.txt.gpg 
gpg: encrypted with 4096-bit RSA key, ID 54AE7D44B93BDBDF, created 
2019-05-30
  "Marco van Hulten (publiko) "
gpg: public key decryption failed: No pinentry
gpg: decryption failed: No secret key

Hi, have you tried runinhg everything in a pure environment, from the 
bootstrap? Guix environment guix --pure should give you an environment where 
none of your system is visible.
