I began implementing first in /sys/classes and that is when I ran into the nested class issue. I then looked at the /sys/devices/system interface point and then sought more information and then ASKED for RFC from the list.
I will now use the /sys/devices/system/edac as my root for my files and controls.
Speaking of controls, edac has them currently in /proc/sys/mc. I have proposed to have them in /sys/devices/system/edac/mc and friends.
My question is: Should I remove entirely my old /proc/sys/mc sysctl tree? Or still maintain the aliases there (which seems weird)?
If I do that, then /etc/sysctl.conf will no longer allow for setting things up there.
Is there going to be a similiar functionality as /etc/sysctl.conf for those items we place in sysfs, in the future?
thanks

PS. These questions on sysfs seem a perfect food stream for your 'HOWTO do kernel development'. Trying to do new entries in sysfs has been a painstaking adventure. After googling the web for info, it definitely has been a bit thin on information on sysfs at the level I am seeking.
