[yocto] Set root password from a recipe

[Mauro Ziliani]

Hi all.

I need to set a well know password for root user.

I follow the istruction to do this with


inherit extra_users

EXTRA_USERS_PARAMS = " \

     usermod -P secret root; \

"


But it does not work.

I think the problem i for usermod

I sse the man page and the -p parameter needs the output of crypt(3) 
function.

While -P parameter (p-uppercase) is not a valid parameter for usermod


Any idea?


Thanks
