I've had examples of needing kgdb but the system being unable to build ports because of what was wrong, including just after an update or install attempt of FreeBSD. I'd be cautious of completely removing references to /usr/libexec/kgdb vs. indicating its use as a last resort, such as when the alternatives are not available and can not readily be made available. Going in another direction . . . On at least one non-tier-1 architecture I've at least once had both kgdb's available but only /usr/libexec/kgdb would work. (I do not remember the details any more.) I'd be cautious of too much tied to tier-1 if some others (still) have such problems. (This last might be tied to my experiments with using clang to target powerpc family members and so might be outside the normal/supported form of building. I just do not remember at this point.) =3D=3D=3D Mark Millard marklmi26-fbsd at yahoo.com ( dsl-only.net went away in early 2018-Mar)
