#From: "@(#)Install	1.56	96/10/11 SMI"
#ident	"%Z%%M%	%I%	%E% SMI"
#
# Author:  Jeff Bonwick
#
#	Please report any bugs to bonwick@eng.
#
# How Install works:
#
#	Install performs the following steps:
#
#	1. Get the list of modules, configuration files, and links
#	   that are desired.
#
#	2. Create the requested subset of /kernel in Install's temp space
#	   (/tmp/Install.username by default.)
#
#	3. Create a tar file (/tmp/Install.username/Install.tar) based on (3).
#
#	4. If -n was specified, exit.  If a target was specified using -T,
#	   rcp the tarfile to the target and exit.  If a target was specified
#	   using -t, rsh to the target machine and untar the tarfile in the
#	   target directory.
#
# If any of these steps fail, Install will give you an error message and,
# in most cases, suggest corrective measures.  Then, you can recover the
# install with "Install -R". (This is not required; it's just faster than
# starting from scratch.)
#
# One final comment:  Unfortunately, tar and I disagree on what
# constitutes a fatal error.  (tar -x will exit 0 even if it can't write
# anything in the current directory.)  Thus, I am reduced to grepping stderr
# for (what I consider) fatal and nonfatal error messages.  If you run into
# a situation where this doesn't behave the way you think it should (either
# an "Install failed" message after a successful install, or an "Install
# complete" message after it bombs), please let me know.

#
# The CDPATH variable causes ksh's `cd' builtin to emit messages to stdout
# under certain circumstances, which can really screw things up; unset it.
#

Usage: Install	[ -w workspace ]
		[ -s srcdir (default: usr/src/uts) ]
		[ -k karch (e.g. sun4u; required if not deducible from pwd) ]
		[ -t target (extract tar file on target, e.g. user@machine:/) ]
		[ -T target (copy tar file to target, e.g. user@machine:/tmp) ]
		[ -n (no target, just create tar file in /tmp (default)) ]
		[ -u (install unix only) ]
		[ -m (install modules only) ]
		[ -a (install everything, i.e. unix + modules (default)) ]
		[ -v (verbose output) ]
		[ -V (REALLY verbose output) ]
		[ -q (quiet (default)) ]
		[ -c (clean up (remove temp files) when done (default) ]
		[ -p (preserve temp files -- useful for debugging) ]
		[ -L (library create: put tarfile in $INSTALL_LIB/env.karch) ]
		[ -l lib (library extract: use $INSTALL_LIB/lib as source) ]
		[ -D libdir (default: $HOME/LibInstall) ]
		[ -d tempdir (Install work area (default: /tmp)) ]
		[ -G glomname (put all files under platform/karch/glomname) ]
		[ -i impl (e.g. sunfire; recommended with -G) ]
		[ -x (update /etc/name_to_major et al) ]
		[ -X (do not update /etc/name_to_major et al (default)) ]
		[ -P (update /etc/path_to_inst -- generally not advisable) ]
		[ -h (help -- prints this message) ]
		[ -R (recover a previous Install) ]
		[ -o objdir (object directory - either obj or debug (the default)) ]
		[ -K (do not copy kmdb) ]
		[ -3 32-bit modules only ]
		[ -6 64-bit modules only ]
		[ list of modules to install ]
