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 On Mon, 1 Mar 2021 at 14:56, Ludovic Courtès <l...@gnu.org> wrote: > Hi Shyam, > > Shyam Saran <syamsaran12...@gmail.com> skribis: > > > Result of application of system build command > > > > $ guix system build ~/tmp/config.scm > > > > 2s > > 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 > > The problem here is that you had: > > (file-system > (mount-point "/") > ;; … > (needed-for-boot? #t) > (dependencies %localmachine-mapped-devices)) > > All the needed-for-boot file systems had all the mapped devices in > ‘dependencies’.
