| Doc Text: |
When turning on selinux from inside the initramfs, the selinux commands used the locale specified for the system. But because the terminal is not yet ready for the locale in the initramfs, the resulting output of the selinux commands was garbled for locales, which differ in fonts to the default linux console. The new dracut initramfs now turns of localization for the selinux commands, which results in readable english messages. The initramfs is not localized anyway.

Japanese cannot be displayed with the console in RHEL6.0/6.1. I think that it is because bogl packages became unsupported in RHEL6. I have two plans for this issue. Plan A :
This simple patch mainly adds force LANG=C to selinux load policy.

# If SELinux is disabled exit now
Plan B: support bogl packages. Uusing the source of bogl of FC15 Rawhide, Japanese was able to be displayed with RHEL6.1. Created attachment 504004 [details]
These are bogl packages used to test.
Using bterm, the garble of dmesg is solved.
I am tending to use LANG=C, because all the rest is not translated anyway. This request was evaluated by Red Hat Product Management for inclusion in a Red Hat Enterprise Linux maintenance release. Product Management has requested further review of this request by Red Hat Engineering, for potential inclusion in a Red Hat Enterprise Linux Update release for currently deployed products. This request is not yet committed for inclusion in an Update release. (In reply to comment #6) > I am tending to use LANG=C, because all the rest is not translated anyway. I think that LANG=C is good in the default setting. I think that a Japanese check of the patch is unnecessary.

The actual command execution is prefixed with LANG=C. Moving to VERIFIED.

Created attachment 504003 [details] garbled screen Description of problem: Using Japanese ja_JP.UTF-8 environment, the characters in load selinux policy message are garbled. Version-Release number of selected component (if applicable): dracut-004-53.el6 How reproducible: always Steps to Reproduce: for example 1. Using Japanese ja_JP.UTF-8 2. SELinux is disabled 3. boot Actual results: Please see attached file(dracut-004-53.el6-selinux-loadpolycy-garbled.JPG) Expected results: Do not garble. Additional info: I think the languages other than Japanese to be garbled. For instance, it is Chinese.
