Perhaps a section on all the sysctl variables and when you would want to tune them. Perhaps a "Tunable Parameters" section. Under what conditions, for example, would you want to increase net.inet.tcp.recvspace? Also, maybe a section on kernel config parameters. For example, from 3.4-STABLE: # Options for the VM subsystem #options PQ_NOOPT # No coloring options PQ_LARGECACHE # color for 512k/16k cache #options PQ_HUGECACHE # color for 1024k/16k cache isn't exactly intuitive. Most admins make tuning changes under duress and either don't have the time or knowledge of C to prowl the sources. I would think that this kind of information would be beneficial and probably sell a number of books;) It would also have the side benefit of distinguishing FreeBSD from the other Open Source alternatives. (The AIX docs _still_ point admins back to the 4.4BSD SMM for file system details -- not Linux HowTos.) A discussion of kernel parameters that are beneficial in emulation would be helpful, but I think any specific detail would probably date the book. Maybe a SYSV vs BSD discussion, viz a viz IPC/shared memory, etc., would be helpful as well as living with FreeBSD in an IPX/token ring world (also dated) as such things still exist. Think in terms of the reasonably competent admin who is new to FreeBSD and isn't a kernel hacker or C wizard, and, probably, under the gun to solve a problem. Sorry, this is only a wish list of what I need now;) -- Jay To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
