Description of problem:
After I upgraded to Fedora 17, I started having the following warning


SELinux is preventing acpid from read access on the lnk_file /var/lock.

*****  Plugin restorecon (94.8 confidence) suggests  *************************

If si desidera sistemare l'etichetta. 
L'etichetta predefinita di /var/lock dovrebbe essere var_lock_t.
Then è possibile avviare restorecon.
Do
# /sbin/restorecon -v /var/lock

*****  Plugin catchall_labels (5.21 confidence) suggests  ********************

If you want to allow acpid to have read access on the lock lnk_file
Then e' necessario modificare l'etichetta su /var/lock
Do
# semanage fcontext -a -t TIPO_FILE '/var/lock'
dove TIPO_FILE è uno dei seguenti: var_run_t, mta_exec_type, device_t, etc_runtime_t, domain, abrt_t, ld_so_t, lib_t, proc_t, root_t, udev_var_run_t, exec_type, modules_conf_t, var_run_t, var_run_t, textrel_shlib_t, rpm_script_tmp_t, cgroup_t, device_t, devlog_t, hwdata_t, locale_t, var_lock_t, apmd_t, bin_t, etc_t, init_t, ld_so_t, lib_t, proc_t, sysfs_t, udev_t, var_run_t, cert_t, etc_t, device_t, var_run_t, var_run_t, var_run_t, cgroup_t, init_t, init_t. 
Quindi eseguire: 
restorecon -v '/var/lock'


*****  Plugin catchall (1.44 confidence) suggests  ***************************

If si crede che acpid dovrebbe avere possibilità di accesso read sui lock lnk_file in modo predefinito.
Then si dovrebbe riportare il problema come bug.
E' possibile generare un modulo di politica locale per consentire questo accesso.
Do
consentire questo accesso per il momento eseguendo:
# grep acpid /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
