I added the strongswan recipe to the image but I cannot start the ipsec service

IMAGE\_INSTALL\_append = “strongswan”

When I type the command “ipsec start”, I get the following error:

Starting strongSwan 5.5.0 IPsec [starter]…  
no netkey IPsec stack detected  
no KLIPS IPsec stack detected  
no known IPsec stack detected, ignoring!

according to this article, this error is safe to ignore:

The issue is widely discussed if you google and it is not specific to Digi product, so this is probably wrong forum to look for the answer.
