Hi list In a system configuration I won't to add a password file from a gpg encrypted file in the following manner: (service radicale-service-type (radicale-configuration (config-file (mixed-text-file "radicale.conf" " [auth] type = htpasswd htpasswd_filename = " (local-file "my-password.gpg ") " htpasswd_encryption = plain ")))) This obviously does not work, but how would I achieve to call gpg --decrypt --quiet inside the mixed-text-file?
