Make utility - some Qs togurus..
(Sorry for previous not on enlish! I did not realized it is english forum. )
I am looking for help with Make utility. I could not get help from the 'man' pages.
1. About Macro (as a variable): It is clear about defining any macro in beginning or in command line, but isn't it no way to redefine a macro during a processing?
I would need to setup some indicator variable in a dependency section and make some action in futher processing depend on its value.
Example:
IND1=0
SECT_0: DEP_1
<command>; \
<command>; \
if [ IND1 -eq 1 ]; then <command>; fi

DEP_1:
<command>; \
IND1=1
It comes out that the re-definition IND1 is not heppening. Maybe I should do it differently?

Another related problem that it seems there is no way to change an environment variable from any section. Seems that any section is processed in separate subshell?! Is it true?

So, is there any way to have a some kind of 'variable' in makefile, not just a 'constant' as it looks like with macro?

2. Initialization section: I know, it is .INIT: ..., but how to exit makefile if it would be nessesary or prevent to execute all available section if makefile is ran with no specific section name?

root_archive

root_archive(1M)														  root_archive(1M)

NAME

       root_archive - manage bootable miniroot archives

SYNOPSIS

       /boot/solaris/bin/root_archive  pack  archive root

       /boot/solaris/bin/root_archive  unpack  archive root

       /boot/solaris/bin/root_archive  packmedia  solaris_image root

       /boot/solaris/bin/root_archive  unpackmedia  solaris_image root

       The  root_archive  utility is used to manage bootable miniroot archives and is currently only available on  platforms. The utility can pack
       and unpack boot/root archives in both ufs and hsfs (iso9660) format. It will always generate ufs archives.

       root_archive also uses the lofi file driver to export a file as a block device (see lofi(7D)) and mount to mount or  unmount  file  systems
       and remote resources (see mount(1M)). root_archive requires the same privileges that are needed to run these commands.

SUBCOMMANDS

       The root_archive command has the following subcommands:

       pack archive root

	   Pack from the image found under the root directory to the archive.

       unpack archive root

	   Unpack from the archive to an unpacked image under the root directory.

       packmedia solaris_image root

	   Pack the solaris image to the root directory.

       unpackmedia solaris_image root

	   Unpack the solaris image from the root directory.

       For  packmedia  and  unpackmedia,  other items that do not go into the ramdisk image are copied or uncopied (see cpio(1)) as well. Specifi-
       cally, this includes all the packaging databases needed for pkgadd and the other packaging utilities to succeed which are not used  in  the
       running and hence pruned to conserve memory.

EXAMPLES

       Example 1: Unpacking the Solaris x86 install image

       The following command unpacks the current Solaris image from the root directory:

       # root_archive unpackmedia 
       /export/nv/solarisdvd.nvx_dvd/latest /export/Boot

       Where  /export/nv/solarisdvd.nvx_dvd/latest  represents	a path to a Solaris x86 install image and /export/Boot is a directory that will be
       purged or created, as necessary.

       Example 2: Packing the Solaris x86 install image

       The following command packs the current Solaris image to the root directory:

       # root_archive packmedia 
       /export/nv/solarisdvd.nvx_dvd/latest /export/Boot

       The following exit values are returned:

       0

	   The command completed successfully.

       1

	   The command exited due to an error.
