Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-hackers@FreeBSD.ORG Precedence: bulk List-ID: List-Archive: (Web Archive) List-Help: (List Instructions) List-Subscribe: List-Unsubscribe: X-Loop: FreeBSD.ORG Sorry if this is a newbie question: I'm looking to tune (amongst others) kern.ipc.semmni; looking at the code (sys/kern/sysv_sem.c) the value seems pretty hardwired - proof against anything short of a kernel rebuild. The man page for loader(8) and tuning(7), there's a reasonably small set of tunable sysctls that are settable as the kernel loads. My question is: is this list definitive? - or does the loader perform some boot-time magic* to locate and set other sysctls? As well as (or instead of) a simple "yes" or "no", I'd appreciate a pointer as to the right bit of the source tree to be looking through. Alas, it's about 20 years since I last looked at Forth :-( Cheers, jan * ok, some _more_ boottime magic -- jan grant, ILRT, University of Bristol. http://www.ilrt.bris.ac.uk/ Tel +44(0)117 9287088 Fax +44 (0)117 9287112 RFC822 jan.grant@bris.ac.uk New Freedom of Information Act: theirs, to yours.
