The problem with doing that is you need to set everything in one go.
Separating all those fields into different sysfs attributes will have
a problem with synchronization.

One workaround is to have another attribute 'Activate'. Nothing is set
until the 'Activate' attribute is written to.  There is still the problem
of another process changing the other attributes behind the back of the
original process.
