A couple user land tools might barf on you (listed below). Other than that, it's generally considered very safe. The quintessential test-case is running an 8.2 jail under an 8.3 host. We do this all the time with various releases (again, most-problematic utilities listed below). > - What are user land tools those not match with 8.3 kernel on freebsd > 8.2 system…? > top and ps might complain about procsize mismatch. netstat has been known to have problems if the gap is too wide. That's about all that I can think off the top of my head. The quick solution is to just grab the 8.3-R copies of top, ps, and netstat *IFF* they cause problems (e.g., ps immediately dies with "procsize mismatch" error). -- Devin P.S. Been doing this kind of mismatching of kernel/userland for YEARS (all the way back to 4.4/4.8) and top and ps always prove to be problematic. _____________ The information contained in this message is proprietary and/or confidential.
