[Kea-users] Problem using 'config-set' in API

[Wlodek Wencel]

Hi,

the reservation-add command will accomplish what you need. However, it's 
important to note that if you're utilizing a JSON configuration backend, 
you must use the config-write command to save any reservations added via 
the reservation-add command. Failing to do so will result in the loss of 
those reservations upon restarting Kea. If you're using a database to 
store host reservations, there is no need to use the config-write command.
