As mentioned I had removed all dependency for root "/" fs
but result is same
$ guix system build ~/tmp/config.scm
guix system: warning: the following groups appear more than once: users
guix system: error: service 'swap-/dev/mapper/guix-swap' requires
'device-mapping-guix-swap', which is not provided by any service
Then again removed all dependencies from all fs /var /gnu /tmp etc
But the result is the same.
$ guix system build ~/tmp/config.scm
guix system: warning: the following groups appear more than once: users
guix system: error: service 'swap-/dev/mapper/guix-swap' requires
'device-mapping-guix-swap', which is not provided by any service
Thanks
