When I change the root password I'm using the command that you specify "passwd root" and enter a new password. After that, I execute the "exec init" command in U-Boot shell to boot all the linux system. At login, I put the new password, but I cannot log!!!!!
After a restart, I stop the u-boot process to start shell (init=/bin/sh) and cat the /etc/shadow file, and the root password doesn't change (is the old). What I'm doing wrong?
