Description Adam Williamson 2010-02-26 20:26:40 UTC

SELinux is preventing /usr/bin/python "relabelto" access on vg_testbed-lv_root.

Detailed Description:

[SELinux is in permissive mode. This access was not denied.]

SELinux denied access requested by anaconda. It is not expected that this access
is required by anaconda 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 access.

Allowing Access:

You can generate a local policy module to allow this access - see FAQ
(http://docs.fedoraproject.org/selinux-faq-fc5/#id2961385) Please file a bug

Comment 1 Adam Williamson 2010-02-26 20:28:10 UTC
This alert is shown at the end of install from the F13 Alpha live image, so it's pretty visible, but since - as it says - SELinux is in permissive mode on a live boot, it shouldn't break anything. We should clean it up for cosmetic reasons, though.

Comment 2 Daniel Walsh 2010-02-26 20:45:04 UTC
Strange since it should not happen.   A link file should never be labeled fixed_disk_device_t.

Comment 3 Daniel Walsh 2010-02-26 20:48:41 UTC
	Fixed in selinux-policy-3.7.10-6.fc13.noarch

Miroslav can you change the line in devices.te

allow devices_unconfined_type device_node:{ blk_file chr_file lnk_file } *;

Ok, also added to selinux-policy-3.6.32-96.fc12.
