What you see is probably the kernel modules being compiled. All modules are normally always compiled and installed regardless of the kernel configuration. (One can change this using various options in /etc/make.conf, but unless disk space is really tight or the time needed to compile a kernel has to be reduced as much as possible, there is not really any need to disable various modules from being built.) To find all the options that can be used in the kernel config file you can look at /usr/src/sys/conf/NOTES (for machine-independent options) and /usr/src/sys/i386/conf/NOTES (for i386-specific options.) You should also read the FreeBSD handbook's chapter on kernel configuration if you have not already done so: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html -- <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
