It depends what you're changing. You can safely use nightly -i to do
an incremental build, which will (probably) take much less time than
the clobber build. Or you can just use bldenv and run dmake setup
install from usr/src. If you're changing the kernel, you'll want to
rebuild in usr/src/uts/{intel,sun4u,sun4v}/genunix and
usr/src/uts/{i86pc,sun4u,sun4u/<platform>}/unix. Depending on what
you've changed, you may have to refresh your proto area's headers and
rebuild userland components and/or build other kernel modules as well.
In general nightly -i is the safer option, but if your changes are
limited in scope it will be faster to rebuild only what you've
changed. This is especially true if you're changing only a single
module's code rather than something in the kernel proper.
