This is true. They also depend on the KLDs (a KLD can add new sysctl variables and/or trees). > What are some kernel options that carry >along their own sysctl trees, if this is the case? This is not as easy to answer, and the following relates to -current. Merging the set of files that define sysctl valiables (via the SYSCTL_...() macros) with the generic and architecture-dependent configuration files produces a list of the following options (some of which are architecture-dependent): apm, bktr, bridge, card, ccd, cd, compat_linux, cs, dgb, dgm, dummynet, ether, ext2fs, ffs, fla, inet, ipfilter, ipfirewall, ipx, loran, ncr, nfs, nsio, nullfs, pci, profiling-routine, si, sio, smp, tun, umapfs, userconfig, vlan and wl. (I have a list of the 58 actual files if you're interested). In addition, the following modules define sysctl variables: bktr, if_tun, ipfw, linux, nfs, null and umap. (Based on objdump reporting a .set.sysctl_??? section_). Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
