The root password how to set during compilation the Openstlinux

[MWoło.2]

Hello,

currently, I'm in the production phase of my product which is based on stm32mp153. Unfortunately, I have a huge problem with setting the password for root.

First I commented debug-tweks in local.conf.

I added 

INHERIT += "extrausers"
EXTRA_USERS_PARAMS = " \
    usermod -p '$5$otifn3fxcID0nu0c$QUDR.mLMbgEgl26XPEX6Rm6ASUB0ab8UFtQHdoEOBt4' root; \
"

hashed or not based password but I can't login into root using ssh.

Then I discovered that I could still log in through the serial console without providing anything. I found and commented 'serial-getty@.service'

line

ExecStart=-/sbin/agetty -8 --autologin root -L --keep-baud %I @BAUDRATE@ $TERM

to

ExecStart=-/sbin/agetty -8 -L --keep-baud %I @BAUDRATE@ $TERM

 Additionally, I updated sshd_config file line

PermitRootLogin prohibit-password

to

PermitRootLogin yes

 And finally, the result is that I can't log in via serial and ssh.

I read some issues from the link

https://www.blaess.fr/christophe/yocto-lab/index.html

without success.

My intention is simple how to modify local.conf or any other file to login via ssh and serial on root using password.

PS. I discover also that the capital letter P cause a problem with st-image-weston compilation

usermod -P

Hi, @MWoło.2 

as far as I know, you should escape the '$' by '\' in the usermod line
