Failed to call ScheduleShutdown in logind, proceeding with immediate shutdown: Access denied

　　装了fedora23后定时关机：sudo shutdown -h +60

　　弹出如下信息后立刻就关机了：

Failed to call ScheduleShutdown in logind, proceeding with immediate shutdown: Access denied
　　
　　
　　Google一下，问题出在selinux。看下日志：

journalctl | grep -i avc

　　找到问题所在：

Nov 26 12:26:57 RedBase audit[752]: AVC avc:  denied  { create } for  pid=752 comm="systemd-logind" name=".#scheduledKNqxuo" scontext=system_u:system_r:systemd_logind_t:s0 tcontext=system_u:object_r:init_var_run_t:s0 tclass=file permissive=0

　　在/var/log/audit/audit.log中也找到相应信息：

# sudo audit2why < /var/log/audit/audit.log

type=AVC msg=audit(1448512017.541:564): avc:  denied  { create } for  pid=752 comm="systemd-logind" name=".#scheduledKNqxuo" scontext=system_u:system_r:systemd_logind_t:s0 tcontext=system_u:object_r:init_var_run_t:s0 tclass=file permissive=0

    Was caused by:
        Missing type enforcement (TE) allow rule.

        You can use audit2allow to generate a loadable module to allow this access.

　　那我们就使用audit2allow来生成相应模块来解决这个问题吧：

# cd /etc/selinux/targeted/policy
# grep systemd-logind /var/log/audit/audit.log | audit2allow -M mypol
# sudo semodule -i mypol.pp

 　　搞定，这样在当前目录下就生成了两个文件：mypol.pp  mypol.te,看看：

# vim mypol.te

#============= systemd_logind_t ==============
allow systemd_logind_t init_var_run_t:file create;

　　试验一下：

# sestatus
SELinux status:                 enabled
SELinuxfs mount:                /sys/fs/selinux

# shutdown -h +30
Shutdown scheduled for Mon 2015-11-30 13:31:26 CST, use 'shutdown -c' to cancel.

　　Bingo!这样以后晚上工作没完成时，就可以让我的电脑多加一下班啦 ：）
