Hi,

I'm testing guix system image with the attachend config, and I get
this error:

/mnt/root/man.config.scm:35:14: warning: the 'target' field is 
deprecated, please use 'targets' instead
guix system: warning: Consider running 'guix pull' followed by
'guix system reconfigure' to get up-to-date packages and security updates.

guix system: error: service 'swap-/swapfile' requires 'file-system-/', 
which is not provided by any service

I can't find anything regarding a file-system-/ service. I do have a 
rootpartition in 'file-systems'. Why is that not sufficient?

If I remove the dependency in swap-devices, it builds, though the system 
gets stuck on boot shortly after generating ssh keys. Picture is 
attached. Any hints for that problem?
