Setting root password
What is the best way to set the root password for an image during build time?
I have come across this snippet:
ROOTFS_POSTPROCESS_COMMAND += " \
sed 's%^root:[^:]*:%root:${PASSWD}:%' \
< ${IMAGE_ROOTFS}/etc/shadow \
> ${IMAGE_ROOTFS}/etc/shadow.new;\
mv ${IMAGE_ROOTFS}/etc/shadow.new ${IMAGE_ROOTFS}/etc/shadow ;"but it feels a bit hacky... is there no defined way to do this cleanly?
Cheers,
Jack.

indeed, gnu sed has had a -i option for some years now, no needs to that intermediate file.

What about using EXTRA_USERS_PARAMS?
E.g.
1. Get the encrypted password.
(One way to get the encrypted password is using openssl, of course you can use other methods.) openssl passwd -1 root
$1$QauDU/Ig$KEeg.OaCLFkNwSXW4xYRu1
2. Add to local.conf the following lines. Note the '$' sign should be escaped.
INHERIT += "extrausers"EXTRA_USERS_PARAMS = "usermod -p '\$1\$QauDU/Ig\$KEeg.OaCLFkNwSXW4xYRu1' root;"
