>Changes to the kernel often require changes to
<SPAN

version of <SPAN
CLASS="APPLICATION"
>modutils</SPAN
> whenever you upgrade
your kernel. <SPAN
CLASS="APPLICATION"
>modutils</SPAN
> is always backward
compatible (it works with older kernels), so there's no such thing as
having too new a <SPAN

>modutils</SPAN
>.</P

>Warning: <B
CLASS="COMMAND"
>modprobe</B
> invokes <B
CLASS="COMMAND"
>insmod</B

and has its location hardcoded as <TT
CLASS="FILENAME"

>.
There may be other instances in <SPAN
CLASS="APPLICATION"
>modutils</SPAN
> of
the PATH not being used to find programs. So either modify the source
code of <SPAN
CLASS="APPLICATION"
>modutils</SPAN
> before you build it, or
make sure you install the programs in their conventional directories.</P
