Red Hat Bugzilla – Bug 57405
Jumbled input after switching to single user mode.
Last modified: 2014-03-16 22:24:41 EDT
Description of Problem:
After switching from run-level 5 (init5) to single user (init1), the
keyboard inputs get jumbled when the user presses enter. For example,
when you attempt to change to run-level 5 by entering init 5, you may get
something like ti5ni echoed back to the screen. It is the character
sequence that is echoed that the system attempts to exec, consequently you
can do next to nothing until you figure out the sequence.
Another example we worked through was reboot.
user types: reboot
system echoes something weird.
Eventually, we figured out if we typed oroetb the system would reboot.
The sequence appears to be 1,3,5,7,... 2,4,6,8,... but changes based on
what is still resident in the input buffer...
Version-Release number of selected component (if applicable):
RC-3. qa1129, qa1207.
Steps to Reproduce:
1. boot to init 5
2. change to init 1
3. type something intelligible and hit return
4. observe what is spit out...
expect what the user typed to be echoed and exec'd.
This should be fixed with the util-linux errata. It's a login problem.
