Its not really a big deal rather the consequence of genkernel telling you what version of the linux kernel its building before running make mrproper, after it starts menuconfig and you go into (General setup -> () Local version - append to kernel release): the value is empty as it should be. Reproducible: Always
I believe this happens because KV (kernel version) is set based on kerncache.config rather than the live Makefile, when KERNCACHE is found from a previous run. This code is in /usr/share/genkernel/gen_determineargs.sh I'm not sure that we gain anything, performance-wise, by pulling these values from kerncache.config rather than the live Makefile. Thoughts on this, genkernel team and original reporter?
Is this a dupe of bug 263927?

If you already have compiled that KV, genkernel maybe use your existing configuration from /etc/kernels (depends on other settings like --mrproper). Once your new kernel was built and you are saving configs (--save-config), we will save the used configuration in /etc/kernels/kernel-config-${ARCH}-${KV}. If you used --menuconfig during genkernel run to change kernel options like CONFIG_LOCALVERSION or CONFIG_LOCALVERSION_AUTO or have modified kernel's Makefile manually to change version, KV is subject to change once genkernel has called 'make prepare'. With this change we will tell user when KV has changed to end confusion like shown in bug 521778.

It is enough to read include/linux/version.h or include/linux/utsrelease.h from $KERNEL_OUTPUTDIR which is either set to $KERNEL_DIR or is a separate directory in which case there will be no files created in $KERNEL_DIR. - Set marker if KV will change to allow for user notification to avoid confusion.
