- Teach it to read gang blocks. (essentially untested) If you see "ZFS: gang block detected!", please let me know, so we can either remove the printf if it works, or fix it if it doesn't. - If multiple partitions exist on a disk, probe them all. We also need to reset dsk->start to 0 to read the right sector here. - With GPT, we can have 128 partitions. - If the bootfs property has ever been set on a pool it seems that it never goes away. zpool won't allow you to add to the pool with the bootfs property set. However, if you clear the property back to default we end up getting 0 for the object number and read a bogus block pointer and fail to boot. - Fix some error printfs. The printf in the loader is only capable of c,s and u formats. - Teach printf how to display %llu Reviewed by: dfr, jhb MFC after: 2 weeks
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 ``world'' target should only be used in cases where the source tree has not changed from the currently running version. See: http://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, 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.
