# Customize: customize dialect's machine.h header file.
#
# Allows easy modification of some important compile-time definitions for
# lsof, made in the dialect's machine.h header file, including:
#
#	HASSECURITY	the security option
#	HASNOSOCKSECURITY
#			the socket oberalization of HASSECURITY
#	HASDCACHE	enabling/disabling the device cache file
#			(Note: changing the device cache file option isn't
#			       offered when machine.h contains NEVER_HASDCACHE
#			       anywhere, including in a comment.)
#	HASENVDC	enabling/disabling device cache path from environment
#	HASKERNIDCK	enabling/disabling the kernel identity check
#			(not done for some dialects)
#	HASPERSDC	enabling/disabling personal device cache path
#			construction
#	HASPERSDCPATH	enabling/disabling additional personal device cache
#			path component
#	HASSYSDC	enabling/disabling system-wide device cache file path
#	HASXOPT_ROOT	enabling/disabling root use of the -X option
#	WARNDEVACCESS	enabling inaccessible /dev node warnings
#			(Note: changing the inaccessible /dev/node warning
#			       option isn't offered when machine.h contains
#			       NEVER_WARNDEVACCESS anywhere, including in a
#			       comment.)
#	WARNINGSTATE	enable/disabling default warning message state
#
# Usage: Customize [dialect_directory]
#
# where: dialect_directory (optional) is the directory in which the dialect's
#	 dialect's sources, Makefile and scripts are found

OLD=machine.h
NEW=new_machine.h

# Save optional dialect directory.

You may now customize the machine.h header file for this UNIX
dialect.  The customizations will take effect when you compile
lsof.  You may also choose to skip customization and proceed to
the compilation of lsof.

If you don't know if you need to customize or want to know more
about what you can customize, consult the 00DCACHE, 00FAQ, 00PORTING,
and 00README files of the lsof distribution.  You might also find
it helpful to examine the machine.h header file for the dialect
you're customizing.

You don't need to use this procedure to customize lsof; you can
edit the machine.h header file directly.  If you later decide you
want to use this procedure to customize machine.h, execute the
./Customize script.

HASXOPT is defined.  If the dialect for which you are customizing

of HASXOPT_ROOT to restrict the use of the X option to lsof processes
whose real user ID is root, or enable use of it by all user IDs.

  AIX           the -X option enables the risky operation of letting
		lsof read library entry structures with readx().
		If HASXOPT_ROOT is defined, only processes whose
		real user ID is root will be allowed to use -X.
		If HASXOPT_ROOT is undefined, any process will be
		allowed to use -X.  Consult the 00FAQ file of the

=====================================================================

When HASKERNIDCK is enabled, lsof compares the identity of the
kernel where it was built to the identity of the kernel where it
is running.  This check can detect an lsof executable inappropriate
for the system on which it is being run.

The kernel identity check can take considerable time on some UNIX
dialects -- e.g., AIX -- so there may be occasions when it is
desirable to disable it, in spite of the increased risk of using
an inappropriate lsof executable.
