When the new commands came out, they did start using a new interface
which was versioned for the v2 log code. The old commands will work
with a new kernel, but the new commands will not work with an old
one. When you build commands, the installed kernel has nothing to
do with which version of the system calls the commands will use.

So, use older commands with an old kernel, or use a newer kernel.
