was mistakenly calling the standard isnumber() function to find out if the given 'user' or 'group' were all numeric. This meant that only the first character of the fields were actually checked, so a username of (say) '3com' would look like a number, and thus get mapped to uid=3 (bin) instead of username=3com. This bug was introduced back in freebsd's v1.1. That initial import almost matches netbsd's v1.9, except that an internal isnumber() routine was removed in favor of the standard library version. The thing is, that internal routine was checking the entire string, and not just the first digit. In OpenBSD, isnumber() was eventually renamed to isnumberstr() to make the distinction more obvious, and I'm going to follow that lead. I believe this also happens to remove the last references to isnumber() in the entire freebsd base system. Obtained from: OpenBSD, by a long circuitous route MFC after: 5 days
This is the top level of the FreeBSD source directory. This file was last revised on: $FreeBSD$ 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, the most commonly used one being ``world'', which rebuilds and installs everything in the FreeBSD system from the source tree except the kernel, the kernel-modules and the contents of /etc. 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, documentation for which can be found at: http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html And in the config(8) man page. 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 sample kernel configuration files reside in the sys/<arch>/conf sub-directory (assuming that you've installed the kernel sources), the file named GENERIC being the one used to build your initial installation kernel. The file NOTES contains entries and documentation for all possible devices, not just those commonly used. It is the successor of the ancient LINT file, but in contrast to LINT, it is not buildable as a kernel but a pure reference and documentation file.
