[csw-maintainers] Major adjustment of GAR defaults

[Dagobert Michelsen]

Fellow maintainers,

as it was observed during the talk in Dublin some defaults in GAR are
not really sane and it would be good to adjust them. The following
variables are candidates for adjustment:

* MERGE_SCRIPTS_isa-extra = copy-relocated-only copy-config-only

This is copy-relocated-only at the moment. The present setting just
copies
  $(bindir)/*-config
but not the 64 bit equivalent
  $(bindir)/(sparcv9|amd64)/*-config
This change should be transparent to all packages only fixing
issues about missing *-config for 64 bit.

* MERGE_DIRS_isa-extra = $(libdir)

This is now
  $(bindir) $(libdir) $(sbindir) $(libexecdir)
However, it was felt that most of the time only the libraries need to
be provided for 64 bit and the binaries hence should be excluded for
automatic inclusion.
Adding the old default to build recipes may or may not be good because
there are several other ways to exclude files and it would be
confusing to add them explcitily and later on remove them again.

* CONFIGURE_ARGS = $(DIRPATHS)

This defaults to empty ATM. The number of packages using configure with
no arguments should be really small as this would be a non-standard
build.

* TEST_TARGET = check

The previous target was "test". This can be detected and reset
for Makefiles requiring the old target.

* NOISAEXEC = 1 -> ISAEXEC ?= 0

The current default is to use ISAEXEC when more then one ISA is built.
Again as most of the time libraries are used for multiple ISAs the
defaulting of ISAEXEC is usually considered wrong and should be
enabled together with $(bindir) MERGE_DIRS only when a benefit has
been proven.
The current name is "NOISAEXEC", changing the default to "1" would
require setting "NOISAEXEC = 0" which looks not straight forward.
I tend to invert it to default to "ISAEXEC ?= 0" and allow setting
of "ISAEXEC = 1" in the Makefile. This can be detected and reset
for Makefile using it.

* sysconfdir = /etc/opt/csw
* localstatedir = /var/opt/csw

These have been changed some time ago and should be the default
now. Only very specific packages should stick to /opt/csw/etc
as default and /opt/csw/var should not be used at all.
As the new default should apply to a lot of packages I would
rather not update this automatically.

I plan to do the update in one large swoop.

Thoughts?


Best regards
