Description of problem: If I boot into single-user mode from Grub, I am unable to do things like run the "passwd" command. A strace reveals "Inappropriate ioctl for this device" messages. Version-Release number of selected component (if applicable): RHEL 6.0 How reproducible: Always Steps to Reproduce: 1. At GRUB menu, press spacebar 2. Press a to get to "append" mode 3. Enter a space, then "single" at the end of the line, and press <enter> 4. When you are dropped at the root prompt, enter "passwd" command 5. You get dropped back to the prompt 6. To see the error message, run "strace passwd" and view the stack trace. Actual results: Unable to run the "passwd" command (and probably others) Expected results: Normal single-user functionality Additional info: Tried this in a KVM virtual machine as well as VirtualBox. No physical hardware to test on. RHEL6 2.6.32-71.el6.x86_64
Probably not the right component, as someone else has a working system that has the same version of the init scripts. The $TERM is "linux" on working and non-working system.
I have 2 KVM instances of RHEL 6 - one works perfectly in single, the other has the same problem. All environment vars are identical in both instances. initscripts-9.03.17-1.el6.x86_64 bash-4.1.2-3.el6.x86_64 Package versions identical on both systems. Please contact me if you require more info from either system.
Since RHEL 6.1 External Beta has begun, and this bug remains unresolved, it has been rejected as it is not proposed as exception or blocker. Red Hat invites you to ask your support representative to propose this request, if appropriate and relevant, in the next release of Red Hat Enterprise Linux.
