ovirt-node-iso SELinux build problems

[Fabian Deutsch]

Hey,

for some time now we - the ovirt-node-iso builds - are seeing some
selinux related build problems. They look similar to [1]:

ERROR: policydb magic number 0x000008 does not match expected magic
number 0xf97cff8c or 0xf97cff8d
ERROR: Unable to open policy /sys/fs/selinux/policy.
Traceback (most recent call last):
  File "/sbin/semanage", line 25, in <module>
    import seobject
  File "/usr/lib64/python2.7/site-packages/seobject.py", line 27, in <module>
    import sepolicy
  File "/usr/lib64/python2.7/site-packages/sepolicy/__init__.py", line 65, in <module>
    raise e
ValueError: Failed to read /sys/fs/selinux/policy policy file

A first guess was that the policydb of the host didn't match the
policydb beeing used in the livecd image. But it seems as if this is not
the case, as the problems still occur.
I'm no selinux expert but maybe bug #817485 (RHBz) contains a fix for
this and I'd like to try this.
The following two packages must be installed and be updated to the most
recent version:

yum -y update setools-console setools-libs-python

Could someone install and/or check if they are updated to the latest
versions on our two F18 builders?

Thanks
fabian
