+++ This bug was initially created as a clone of Bug #431556 +++ +++ This bug was initially created as a clone of Bug #172059 +++ Description of problem: Running "BASH_ENV=~/.bashrc TERM=linux /bin/unicode_start" on physical console will not return. Version-Release number of selected component (if applicable): kbd-1.12-21.el5 How reproducible: 100% Steps to Reproduce: 1. Switch to a real virtual terminal (i.e. not ssh or virsh console). 2. Run "TERM=linux BASH_ENV=~/.bashrc /bin/unicode_start" Actual Results: Command never returns. Expected Results: Command should return. Additional info: The problem is that setting BASH_ENV=~/.bashrc runs /etc/profile, which sources /etc/profile.d/lang.sh. If TERM=linux, lang.sh runs /bin/unicode_start sending the whole process into an infinite loop. The resolution is to change the first line of /etc/unicode_start from "#!/bin/bash" to "#!/bin/sh". This seems to be the way upstream (Fedora 12, at least) is written.
