:SELinux is preventing /usr/libexec/udisks-daemon from 'getattr' accesses on the file /LiveOS/ext3fs.img.
:*****  Plugin restorecon (94.8 confidence) suggests  *************************
:If you want to fix the label. 
:/LiveOS/ext3fs.img default label should be etc_runtime_t.
:Then you can run restorecon.
:# /sbin/restorecon -v /LiveOS/ext3fs.img
:*****  Plugin catchall_labels (5.21 confidence) suggests  ********************
:If you want to allow udisks-daemon to have getattr access on the ext3fs.img file
:Then you need to change the label on /LiveOS/ext3fs.img
:# semanage fcontext -a -t FILE_TYPE '/LiveOS/ext3fs.img'
:where FILE_TYPE is one of the following: devicekit_tmp_t, proc_kmsg_t, mount_exec_t, shell_exec_t, system_dbusd_var_lib_t, krb5_conf_t, abrt_var_run_t, dbusd_etc_t, userdomain, fusermount_exec_t, fsadm_exec_t, mtrr_device_t, domain, sysctl_crypto_t, proc_mdstat_t, proc_net_t, policykit_reload_t, mdadm_exec_t, samba_var_t, etc_runtime_t, abrt_t, lib_t, anon_inodefs_t, net_conf_t, udev_var_run_t, file_type, exec_type, abrt_helper_exec_t, ld_so_t, devicekit_var_lib_t, devicekit_var_run_t, dbusd_etc_t, devicekit_disk_t, userdomain, lvm_exec_t, system_dbusd_var_lib_t, textrel_shlib_t, policykit_auth_exec_t, sysctl_fs_t, rpm_script_tmp_t, bin_t, usr_t, cert_t, device_t, locale_t, etc_t, proc_t, sosreport_tmp_t, sysfs_t, virt_image_type, rpm_tmp_t, ld_so_cache_t, etc_t, devicekit_disk_exec_t, udev_exec_t, sssd_public_t, system_cronjob_var_lib_t, policykit_var_lib_t, krb5_host_rcache_t. 
:Then execute: 
:restorecon -v '/LiveOS/ext3fs.img'
:*****  Plugin catchall (1.44 confidence) suggests  ***************************
:If you believe that udisks-daemon should be allowed getattr access on the ext3fs.img file by default.
:Then you should report this as a bug.
:You can generate a local policy module to allow this access.
:allow this access for now by executing:
:# grep udisks-daemon /var/log/audit/audit.log | audit2allow -M mypol
:# semodule -i mypol.pp

Comment 1 Adam Williamson 2011-08-16 01:07:56 UTC
This notification pops up reliably on booting an F16 Alpha RC4 live image. Proposing as a final blocker under criterion "In most cases, there must be no SELinux 'AVC: denied' messages or abrt crash notifications on initial boot and subsequent login". CCing dwalsh, as I'm guessing his fixes to live image creation resp. SELinux may possibly be relevant here.

Comment 2 Daniel Walsh 2011-08-16 12:10:26 UTC
We have a fix for this in 


Comment 3 Robert Lightfoot 2011-08-19 07:14:27 UTC
Still getting with Fedora-16-Alpha-i686-live-Desktop.iso from rc5

Comment 4 Daniel Walsh 2011-08-20 10:55:22 UTC
What policy package do you have installed?

rpm -q selinux-policy

Comment 5 Adam Williamson 2011-08-20 15:30:21 UTC
RC5 has selinux-policy -15, as there were no blocker or NTH bugs fixed by 16 thru 18.
