So today's conversation with my co-worker who built our build system...

Me:OS X build server is not building valid installs.
Him:What's the problem?
Me:The KEXT is not rebuild... I think that Jenkins isn't capable of updating the file because of the permissions the script set when you test compiled it manually... Could you please add Jenkins user to sudoers file or something?
Him:Yes of course, but what should I google?

WTF dude? Do you even think yourself? And for some reason no-one has acces to the build servers configs exept for him and he shows up like 3 times a week...
