If you don't use the Distribution Constructor or
distro_const(1M), feel free to discard this message
now.
With the putback of changeset 958:552c24933bed in
build 156 of the slim_source gate, distro_const(1M) has
been completely re-written to take advantage of the new
Install infrastructure.
What has changed?
-----------------
DC has been re-written to use the CUD (Caiman Unified
Design) components. It is now purely a python application.
The format of the DC manifests has changed and they
are now in the DTD XML format.
In addition to this, a number of outstanding bugs and RFEs[1]
have been fixed that should make the user experience
considerably better.
How do the changes impact me?
-----------------------------
The following are the user visible impacts of this change:
a) '-R' option (resume at next unexecuted step) to
distro_const(1M) has been removed due to lack of use.
b) DC manifests have been renamed to:
dc_livecd.xml
dc_ai_x86.xml
dc_ai_sparc.xml
dc_text_x86.xml
dc_text_sparc.xml
The manifests are now in the DTD format and they are laid
out significantly differently than before.
As a general note, you should only need to edit the
target section of the manifest to specify the location
of the build area, and the software section to specify the
package repository and package list.
c) Existing finalizer scripts are not compatible with the
revised Distribution Constructor. Custom extensions to DC
are easily accomodated by using the custom-script checkpoint,
which is documented here:
http://hub.opensolaris.org/bin/view/Project+caiman/%0D%0AInstructions
d) As was the case with the old DC, this revision of DC requires
that the Solaris build version that you're running on your
build machine must be the same as that of the media
you're building. For instance, if you are intending to
build media based on 151, your build machine must be
running 151.
While build version mismatch will not prevent DC
from running, it is *strongly* discouraged as it can often
lead to unpredictable results that are hard to diagnose.
