still methodically perusing the courseware i'll be teaching week after next, right now going through section on kobjects and sysfs and reading the kernel doc file Documentation/sysfs-rules.txt, which mentions a proposed /sys/subsystem hierarchy which, when(?) it exists, will obsolete /sys/{bus,class,block}. so what's the current status of this subsystem directory? is there a timeline for this? just curious. rday -- ======================================================================== Robert P.
