Description of problem:
SELinux is preventing /usr/sbin/usbmuxd from 'write' accesses on the file usbmuxd.pid.

*****  Plugin catchall (100. confidence) suggests  ***************************

If 您确定应默认允许 usbmuxd write 访问 usbmuxd.pid file。
Then 您应该将这个情况作为 bug 报告。
您可以生成本地策略模块允许这个访问。
Do
请执行以下命令此时允许这个访问：
# grep usbmuxd /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
