Add default user settings templates
accountsservice/accountsservice#63 (closed) has added support for default user settings templates in accountsservice.
Malcontent could use that to enable parental controls on new standard (non-admin) users by default, if configured to.
Since installing a new template needs write access to /etc
(or a similar system directory), the likely approach would be to write a suexec helper program which checks the malcontent configuration and either installs or removes /etc/AccountsService/user-templates/standard
depending on whether it’s enabled.
