As a rule of thumb, I always BFU to (usually) the closest daily build before using Install. Being inside the Sun firewall, I have the advantage of access to nightly builds generated by the ON gate staff, though. If I were doing a project outside SWAN, I'd use BFU the first time, and then if my changes were kernel-only, Install to test intermediate builds. After syncing up with the gate, I'd run a non-incremental nightly(1), BFU the results, then Install from there. If your changes cross the U-K boundry, you typically know it; the above is mostly to save you from unexpected dependencies from *other* putbacks. Cheers, - jonathan
