And I think we should go t= he > failsafe route. This is UN*X, not Windows. UN*X tends to allow a certain bit of foot-shoot= ing=20 to enable people to get useful things done. It seems that since these=20 targets have the same semantics as installworld they should follow the same= =20 policy. A user can already blow their feet off in a much worse fashion by= =20 forgetting TARGET_ARCH when doing an installworld. The fact that we don't= =20 have lots of complaints about that particular case now indicates that your= =20 fears are probably not well-founded. If someone is doing cross-builds and= =20 cross-installs, I think we can expect them to be able to set TARGET_ARCH=20 correctly for the delete-foo targets since they already have to be setting = it=20 correctly for buildworld, buildkernel, installworld, and installkernel. =2D-=20 John Baldwin <jhb@FreeBSD.org> =A0<>< =A0http://www.FreeBSD.org/~jhb/ "Power Users Use the Power to Serve" =A0=3D =A0http://www.FreeBSD.org
