In general when you make an updated kernel you should rebuild and install
world too. This doesn't apply to building a different (custom) kernel when
world has not changed. Okay, it is often true that within major versions
you can run with an updated kernel on the old world for a long time without
encountering a problem, but problems from kernel-world mismatch are not
If and when you install the sources, check the procedures in UPADATING (near
the bottom) for best practices procedure.

With the above concern about kernel-world mismatch in mind, yes this is
likely to work, but the best practice would be to make a release. This
should work even if there is a minor, perhaps unknown, variation in
