Hi, I remember back in the days, there was a neat trick to recover a lost root password, or more exactly, redefine a new password for root. 1. In the bootloader, boot the system with the 'init=/bin/bash' kernel argument. 2. Remount the root partition in read-write mode: # mount -o remount,rw / 3. Set the password for root: # passwd 4. Remount the root partition in read-only mode: # mount -o remount,ro / 5. Switch off the computer. I tried this out of curiosity on a CentOS 7 sandbox machine, and this doesn't seem to work anymore. I can boot to a 'bash' console and set the password OK. But this password doesn't seem to work on the subsequent normal boot. Anybody knows why this is so?
