postinstall -- check and fix installation after system upgrades SYNOPSIS
postinstall [-a arch] [-d destdir] [-m machine] [-s {srcdir | tgzdir | tgzfile}] operation [item [...]] DESCRIPTION
The postinstall utility performs post-installation checks and/or fixes on a system's configuration files. It is especially useful after sys- tem upgrades, e.g. after updating from NetBSD 1.6.2 to NetBSD 2.0. The items to check or fix are divided in two groups: enabled by default and disabled by default. The latter are items that are dangerous for some reason, for example because they remove files which may be still in use. If no items are provided, the default checks or fixes are applied. Those which are disabled by default must be provided explicitly. Supported options: -a arch MACHINE_ARCH. Defaults to machine of the host operating system. -d destdir Destination directory to check. Defaults to /. -m machine MACHINE. Defaults to machine of the host operating system. -s {srcdir | tgzdir | tgzfile} The location of the reference files, or the NetBSD source files used to create the reference files. This may be speci- fied in one of three ways: -s srcdir The top level directory of the NetBSD source tree. By default this is /usr/src. -s tgzdir A directory in which reference files have been extracted from a binary distribution of NetBSD. The files that are distributed in the ``etc.tgz'' set file must be present. The files that are distributed in the ``xetc.tgz'' set file are optional. -s tgzfile The location of a set file (or ``tgz file'') such as ``etc.tgz'' or ``xetc.tgz'' from a binary distribu- tion of NetBSD. Each set file is a compressed archive containing reference files, which will be extracted to the temproot directory. Multiple -s options may be used to specify multiple set files. The ``etc.tgz'' set file must be specified. The ``xetc.tgz'' set file is optional. The operation argument may be one of: check Perform post-installation checks on items. diff [diff(1) options] Similar to check, but also show the differences between the files. fix Apply fixes that check determines need to be applied. Not all items can be automatically fixed by postinstall, and in some cases an error will be reported, after which manual intervention will be required. Conflicts between existing files in the target file system and new files from the NetBSD distribution are resolved by replac- ing the existing file with the new file; there is no attempt to merge the files. See etcupdate(8) for an alternative update method that is able to merge files. help Display a short help. list List available items, showing if they are enabled or disabled by default. usage Same as help. EXIT STATUS
The postinstall utility exits 0 on success, and >0 if an error occurs or a problem was found. SEE ALSO
etcupdate(8) HISTORY
The postinstall utility first appeared in NetBSD 1.6. In NetBSD 4.0, the -s tgzfile option was added. In NetBSD 5.0, the ability to specify multiple colon-separated files with a single -s option was deprecated. BSD

sysinst -- install or upgrade a NetBSD system SYNOPSIS
sysinst [-D] [-f deffile] [-r releasename] DESCRIPTION
sysinst is a menu-based program that may be used to install or upgrade a NetBSD system. It is usually invoked automatically when the system is booted from appropriate installation media. sysinst is usually not present on a NetBSD system that has been fully installed. OPTIONS
-D Switch on debugging. -r releasename Set the releasename if it is different to the one compiled. Currently unused. -f deffile Set a file for definitions other than the defaults. See DEFINITION FILE for its format. DEFINITION FILE
The definition file is used to set several other names and directories to search for. You can specify any of the options in the file. They are stored as: option = value pairs. In this description, REL and MACH are the release and architecture respectively, determined by the image sysinst is used on. option name default value description release REL Release name (also set by -r releasename). machine MACH Machine architecture xfer dir /usr/INSTALL Transfer dir ext dir Extract dir (will usually be set later on) ftp host ftp host for fetching files ftp dir pub/NetBSD/NetBSD-REL ftp directory for fetching files ftp prefix /MACH/binary/sets directory to look for sets. Note that this is used for all kinds of fetching (CDs, local FS, ...), not only ftp. ftp user ftp ftp user for connecting ftp pass - ftp password ftp proxy - ftp proxy nfs host - nfs host for fetching via nfs nfs dir /bsd/release nfs directory for fetching files cd dev cd0a name of the CD device for fetching files fd dev /dev/fd0a name of floppy for fetching files local dev - Other device to be mounted for fetching files local fs ffs FS-type for local dev local dir release Directory to look for in the mounted local fs targetroot mount /targetroot Directory to mount target root dir to dist postfix .tgz Suffix of set files to be extracted diskname mydisk disktab(5) diskname to use for target disk SEE ALSO
