If you say yes here, support for the both manual and automatic

This part of the code wasn't carefully reviewed and tested yet,
so enabling this option is strongly discouraged on production
servers. Only developers and testers should enable it for the
time being.
Please also note that this option will create sysfs attribute
files which may change in the future, so you shouldn't rely
on them being stable.
