How to manage user settings

Send a user-settings-command message containing an assert or retract record containing the setting assertion to add or remove. Use the ! operator of the configuration language to send a message (as opposed to make an assertion):

! <user-settings-command <assert <mobile-data-enabled>>>
! <user-settings-command <assert <mobile-data-apn "internet">>>
! <user-settings-command <retract <mobile-data-enabled>>>

In future, a command-line tool for sending such messages will be provided; for now, create temporary configuration language scripts in /run/etc/syndicate/services:

echo '! <user-settings-command <assert <mobile-data-enabled>>>' > $THROCK
sleep 1
rm -f $THROCK
