Hi!
If I create a configfs subsystem with some items and attributes in
there, is it possible to backup and restore them in user space?
My first experiments say no:
- rsync: read errors mapping "/sys/kernel/config/my/item": No data
available
- tar: short read
- cp: skipping file '/sys/kernel/config/my/item', as it was replaced
while being copied
But maybe I miss something here?
Cheers!
Lars
