I have a couple of questions on using dependencies in confg.scm
file-system definitions.
...
* How do I specify that 'mount-point "/"' is required before mounting
'mount-point "/mnt/ioSafeDuo"'?
* How do I specify specific mapped-device entries as dependencies for
different file-system entries (e.g. cryptroot for "/" and
ioSafeDuo0{1|2}Data for "/mnt/ioSafeDuo")?
I think I solved the second question by defining the mapped-devices and
putting the variables in both mapped-devices and the file-system dependency.
I tried the same idea with file-system but when I uncomment
%my-file-system-root from the dependency a 'guix system reconfigure'
returns an error "guix system: error: service
'file-system-/mnt/ioSafeDuo' requires 'file-system-/', which is not
provided by any service"
Is this the right approach and what am I missing to specify a
file-system as a dependency?
Current config:
...
(define %my-mapped-device-cryptroot
(mapped-device
(source (uuid
"10d6c832-f8c5-45df-b11f-6119a85de83f"))

(define %my-mapped-device-ioSafeDuoD1Data
