Hello! The kernel version moving the hotplug over to /sys from /proc/sys is probably 2.6.16 (based on the date of the git changes and the release date of the kernel). The exact commit which introduces this is: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0f76e5acf9dc788e664056dda1e461f0bec93948 Please see the commit message which has a nice description.
IIRC the statement that the old /proc/sys interface is obsolete is a bit strong and has been debated if it should be said to be obsolete at all. You are expected to have /proc/sys. Kernel people want to clean up /proc to only contain process information, but the truth is that we'll need to remain backwards compatibility in /proc for many years to go. Being an "early" adopter of /sys probably won't hurt though. HTH, HAND. -- Regards, Andreas Henriksson -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
