POSTINSTALL(8)		  BSD System Manager's Manual		POSTINSTALL(8)

NAME
     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 system
     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 dis‐
     abled by default.	The latter are items that are dangerous for some rea‐
     son, 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 oper‐
			 ating 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 specified 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 dis‐
					tribution 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 distribution of NetBSD.
					Each set file is a compressed archive
					containing reference files, which will
					be extracted to the temproot direc‐
					tory.  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 man‐
		    ual intervention will be required.

		    Conflicts between existing files in the target file system
		    and new files from the NetBSD distribution are resolved by
		    replacing 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 dis‐
		    abled 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.

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.

     In NetBSD 7.0, the ability to specify multiple colon-separated files with
     a single -s option was removed.  Multiple -s options must be used
     instead.
