Could this be specific to the raspberrypi?  I cannot reproduce such
problem using a remote Guix System.  But I just tried using a Buildroot
target I had on hand, and I could reproduce something similar:

--8<---------------cut here---------------start------------->8---
$ ssh-copy-id target
/home/maxim/.guix-profile/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/home/maxim/.guix-profile/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
/home/maxim/.guix-profile/bin/ssh-copy-id: line 251: warning: here-document at line 251 delimited by end-of-file (wanted `EOF')
/home/maxim/.guix-profile/bin/ssh-copy-id: line 250: warning: here-document at line 250 delimited by end-of-file (wanted `EOF')
mkdir: cannot create directory ‘/etc/dropbear’: Permission denied
Pseudo-terminal will not be allocated because stdin is not a terminal.
Warning: Permanently added '10.42.0.243' (ECDSA) to the list of known hosts.
root <at> 10.42.0.243's password: 
-sh: ssh-rsa: not found
--8<---------------cut here---------------end--------------->8---

I think it probably has to do with the script not finding the tools it
expects on the minimal (embedded) environments of the
Rasperrypi/Buildroot.  I'll try to have a closer look soon.

Thanks,

Maxim

It happens with both my gentoo machines as well. But they can copy id's
among each other fine.
