Your logic is a little flawed. Those modules are simply built and placed in /modules for future use. They are not by any means built into the kernel and they don't slow the kernel down any. They also are not a security hazard. If you don't insert the module, it is not running. They don't insert themselves into the kernel. >Any suggestions? Yeah, check out the /etc/make.conf and /etc/defaults/make.conf files. Setting NO_MODULES = true in the /etc/make.conf file will make sure that the modules are not built at all, either will world or kernel. There are other MODULES related options to check out as well. However, remember that many things like linux emulation are normally used as kernel modules under FreeBSD and if you don't explicitly build them into your monolithic kernel you won't be able to use them. Also remember if you're gonna turn off module building that you remove the /modules directory so you don't end up accidentally using old modules with your new monolithic kernel. -- Brandon D.
