@cmnstr GRUB is used yes, here's how to reset root on a V11.1 (CentOS 7) system:
[ol 1]
[li]Shut down the IPOSE[/li]
[li]Boot up and get onto console session (I recommend VMWare Remote Console or Workstation)[/li]
[li]Press e on bootup to change boot options[/li]
[li]Find the 'linux16' line and scroll through to the end of the line, then add 'rd.break setenforce=0'[/li]
[li]Save by pressing enter and then boot by pressing Ctrl+x[/li]
[li]When the terminal starts type:
Code:
mount -o remount,rw /sysroot
chroot /sysroot
passwd root
Enter new password for root
touch /.autorelabel <= THIS IS IMPORTANT TO UPDATE SELINUX
exit
exit
[/li]
[li]System will relabel and reboot, give it time[/li]
[li]Note you CANNOT log into root via the console command line during normal running, always use SSH[/li]
[/ol]
