>Description:
The man page for ld.so.conf claims that you can use <sysctl_variable> for directing library loading. The example shows the use of machdep.fpu_present. Its left to the user to infer that you can only use machdep sysctls.

The man page should be updated to state that its a bug that it only supports machdep entries. Further explain that to enable dynamic sysctl lookups would be a significant performance hit if it were to do so.
>How-To-Repeat:
man ld.so.conf

try installing pkgtools/libkver and wonder how you can enable it without setting LD_PRELOAD.
