From: Izumi Tsutsui <tsutsui%ceres.dti.ne.jp@localhost> Is there any reason why GENERIC on sparc doesn't include options DDB? Most other ports have it in their GENERIC-like kernels.
I believe it was originally so that break or L1+A would drop into the prom (similar to Solaris) and not DDB. I suspect DDB may make more sense now...
