disable root user login
This MR disabled the root login on all pinephone devices by executing passwd --lock root
during first boot.
We tried doing this when we build the images, but that seems to not work right, but manually running the command on the device does work.
So add the command to the post install script for the Pinephone.
Needless to say, that this would have to be done in pinephonepro-post-install
too, if accepted.
PS: Checksum in PKGBUILD is not updated in this MR.
