I have to forward this mail which didn't reach to Austen Dicken who
reported his problem to the Public Forum on SourceForge.
It is very hard for me to reply on the web browser.
I hope he will read this message someday, somewhere...

Subject: aufs Makefile version check causes failure on Gentoo Linux

Hello Austen,
Thank you for your report and patch.
Usually I don't check the Public Forum on SourceForge as I wrote in the
aufs README file, so I'd ask you to join aufs-users ML and post there.
We might waste a lot of time.

When you build aufs for a diffrent version of kernel, you will execute
"make KDIR=..." In this case "uname -r" in local.mk has no meaning, and
aufs build system needs to invoke "make -C ${KDIR} kernelversion" to get
the correct version.
If you generate fs/aufs/Kconfig by "make kconfig" and copy all the
necessary aufs files to your kernel tree, then you don't need local.mk
any more. I guess this is the best solution for you.
