No, the patch is for the user tools only.  You need to use this patch if
you are using beta6 user tools, but have an older kernel version.

What symbols are missing?  I assume you applied the resulting kernel patch
to the kernel source tree, and are compiling the LVM module there?

Yes, this is OK.  Basename has always been a problem.

????  If you are not root, then how do you expect to install a new kernel
or run the LVM user tools????
