Are they similar to the old Xenix and Unix drivers, 'cause those were fun. :-/
Thank you for reminding me. I'll be twitching for the rest of the day. Funny how much outright crap one can remember -- I thought those neurons have long died off out of sheer disgust.
For the mercifully uninitiated, SCO Unix had a baroque system of little configuration files, object modules, a severely handicapped C compiler, and a similarly crippled linker for the purpose of modifyng kernel parameters and installing third-party drivers, both of which required re-linking the whole kernel (sysctl? dynamic data structures? run-time linkable modules? never heard. OK, it was the early '90s, but still.)
SCO, in their infinite wisdom, tried to make driver installation "user friendly": you would unpack the archive, start the installation script, and a few minutes later reboot to a freshly built kernel. Of course this failed to account for buggy scripts, weird configurations, and cargo-cult admins, any of which could make an unholy mess of the system and/or render it unbootable. I've had the dubious pleasure of cleaning up a number of such messes.
