Also, #f is not a string, did you mean =E2=80=98;#f|string=E2=80=99? Also, a limitation: the preshared key will end up in the store, and hence be world-readable. So other users on the same system (other people or compromised system daemons) could now determine the preshared key. Questions: * Could the security limitation be documented? * What security impact does a leaked secret key have? * Does wireguard has some inclusion mechanism, such that the wireguard configuration can =E2=80=98include=E2=80=99 some file outside= the store? * WDYT of verifying that the preshared key looks =E2=80=98reasonable=E2= =80=99 (I guess only a-z0-9 characters, no spaces or newlines, not a bytevector ...) As-is, if I do (preshared-keys (string->utf8 "oops I thought this needs to be bytevector)) then "guix system reconfigure" doesn't give a nice error message, it will just silently produce a broken configuration file.
