than arguing) Coverity found: o Use open + fstat rather than stat + open to avoid any races for a file that's static for the life of the system. This will prevent any problems should someone insert a new device while installing a kernel in the future. o Use strlcpy instead of strcpy as a failsafe to knowing that the strings can't possibly be larger than the buffer due to data source limits (though in the future these limits might be more dynamic). o If we can't find the hints file, return rather than dereference a NULL pointer. o Check for lastmod before calling strcmp in case a PNP entry comes before a module entry. That's not allowed, but within the realm of crazy things programmers do. o Free lastmod before exiting search_hints() to avoid a leak. CID: 1383971, 1383970, 1383969, 1383965, 1383963, 1383960

For copyright information, please see the file COPYRIGHT in this directory (additional copyright information also exists for some sources in this tree - please see the specific source directories for more information).
The Makefile in this directory supports a number of targets for building components (or all) of the FreeBSD source tree. See build(7) and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html for more information, including setting make(1) variables.
The buildkernel and installkernel targets build and install
the kernel and the modules (see below). Please see the top of
the Makefile in this directory for more information on the
standard build targets and compile-time flags.
Building a kernel is a somewhat more involved process. See build(7), config(8), and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html for more information.
Note: If you want to build and install the kernel with the
buildkernel and installkernel targets, you might need to build
world before. More information is available in the handbook.
The kernel configuration files reside in the sys/<arch>/conf
sub-directory. GENERIC is the default configuration used in release builds.
