to multi-volume restores: - In findinode(), keep a copy of header->c_type so that we don't exit the do-while loop until we have processed the current header. Exiting too early leaves curfile.ino set to 0, which confuses the logic in createfiles(), so multi-volume restores with the 'x' command don't work if you follow the instructions and supply the tapes in reverse order. This appears to have been broken by CSRG revision 5.33 tape.c (Oct 1992). - The logic in getvol() for deciding how many records to skip after the volume header was confused; sometimes it would skip too few records and sometimes too many, leading to "resync restore" warnings and missing files. Skip to the next header only when the current action is not `USING'. Work around a dump bug that sets c_count incorrectly in the volume header of the first tape. Some of the problems here date back to at least 1991. - Back out revision 1.23. This appeared to avoid warnings about missing files in the 'rN' verification case, but it made the problems with the 'x' command worse by stopping getvol() from even attempting to find the first inode number on the newly inserted tape. The bug it addressed is fixed by correcting the skipping logic as described above. - Save the value of `tpblksread' in case the wrong volume is supplied, because it is incremented each time we read a volume header. We already saved `blksread' for the same reson. |

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/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 have to build world before. More information is available in the handbook. The sample kernel configuration files reside in the sys/i386/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.
