Thanks Arnd !!
This fix solves the config issue, but adds an unnecessary MODULES
dependency on APPRAISE_MODSIG. APPRAISE_MODSIG can be used for kernel
image(appended signature) as well as for kernel modules.
I am working on the fix. I am sorry for the delay, I got stuck with some
urgent issues early this week.
Thanks & Regards,
