I'm developing a driver on Centos 7: # uname -a && cat /etc/redhat-release Linux czlab04.coveloz.local 3.10.0-123.8.1.el7.x86_64 #1 SMP Mon Sep 22 19:06:58 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux CentOS Linux release 7.0.1406 (Core) When I install my module it's 'tainting' the kernel. Rather than rebuilding the kernel, is there a package that has the kernel available without the module signing enabled? - Jamie
