Description Valent Turkovic 2008-01-22 12:45:32 UTC
Description of problem:
    SELinux is preventing /usr/sbin/semodule (semanage_t) "read write" to socket

Detailed Description
    SELinux denied access requested by /usr/sbin/semodule. It is not expected
    that this access is required by /usr/sbin/semodule and this access may
    signal an intrusion attempt. It is also possible that the specific version
    or configuration of the application is causing it to require additional

Allowing Access
    You can generate a local policy module to allow this access - see
    http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385 Or you can disable
    SELinux protection altogether. Disabling SELinux protection is not
    recommended. Please file a http://bugzilla.redhat.com/bugzilla/enter_bug.cgi
    against this package.

Creating livecd images with SELinux in enforcing mode, does not currently work.
 The problem is you have a shared kernel and the act of creating the CD will
load a different policy then the machine you are creating it on.  

So currently when you create a livecd, you need to put the machine in permissive
mode, And will need to reboot when the machine is finished if you want to put
the machine back in enforcing mode.

I'll try create a fake SELinux policy - just for creation process of the live CD.

Comment 11 Daniel Walsh 2008-07-02 20:06:53 UTC
This is now working in Rawhide, and is back ported to Fedora 9.

With livecd from git repository

Policy works, we are waiting for livecd packaged in rawhide and f9.

Also requires -26 kernel for fedora 9. 

Comment 12 Jeremy Katz 2008-07-03 00:40:37 UTC
livecd-tools for F9 has been pushed and rawhide is in git -- testers from git
appreciated as more indicators to do a rawhide build.  Worst case, I'll be doing
one the end of next week for the alpha freeze

Comment 13 Brad Longo 2008-07-08 02:16:59 UTC
I have the same issue.  When this happened I got all the error output from
livecd-creator and I also saved the error messages from selinux troubleshooter.
 Let me know if you want me to include the info.  

Comment 14 Brad Longo 2008-07-08 03:05:15 UTC
This is strange... the livecd works?!

Comment 15 Bug Zapper 2008-11-26 02:05:19 UTC
This bug appears to have been reported against 'rawhide' during the Fedora 10 development cycle.
Changing version to '10'.
