Care to put together a patch? No. The two are different things, although arguably there should be more integration. The tunable mechanism exists to allow parameters to be set before the kernel starts. Things that are set with tunables tend to be things that used to be statically compiled into the kernel; they're not adjustable once the kernel's up and running. It makes sense to export the values set by tunables into the sysctl MIB, but by their very nature they're not suitable for conversion to sysctls. = Mike -- Where am I, and what am I doing in this handbasket?Received on Thu Jul 03 2003 - 08:49:31 UTC
