An alternative to making a copy of GENERIC and then editing it is to create a new file from scratch containing an "include GENERIC" directive and an appropriate "ident" along with "nooptions" and "nodevice" directives to remove unwanted features and "options" and "device" directives to add additional ones, as outlined at the start of section 8.6 of the FreeBSD Handbook <http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig-config.html>. The PAE config file provides an example of this approach. This way your kernel file shows only the changes you've made to the "standard" kernel and should make it easier to identify the cause of problems. -- Mike Clarke
