Sanjay,
thanks for your help...
we will try to find about why they cannot customize
via DC and which Network Install image...
however, their primary issue is the method to
successfully compress and unpack the zlib files...
is the "lzma compression set to a specific compression
value" considered information internal only to Solaris
or can ISVs use the same method?
is this publicly documented?
thanks...

Sharlene,
The solaris_misc is compressed using lzma compression set to
a specific compression value. We would really like to understand why
DC cannot be used since it was designed to addresses specifically the
kind of issues this customer is facing.
Are you aware that aside from using the dc-manifest, users can add
their own checkpoints and thereby add their code into media ?
When you say Network Install Image - do you mean an AI ISO ?

Dave,
thank you for your quick response!
hope this additional information helps:
this is for a bare metal restore (BMR) feature in a backup
application. They require a Network boot image along
with bootable ISO. Hence they are not using distro
constructor but Network Install Image creation and
customizing it for BMR operations...
their BMR customizations can't be provided via dc-manifest
files so distribution constructor is not useful. What is
the recommended method to compress the zlib files only while
working with the Network Install Image?
they used "root_archive pack / unpack" on Solaris 10 but
those options appear to be removed on Solaris 11...
thanks...

Experts,
we have a partner who needs to pack / unpack the
solarismisc.zlib file on Solaris 11 - the partner has
found that:
- root_archive unpack gives:
size before: 20MB
size after: 204MB
- root_archive pack gives errors and size of 27MB
- cannot mount newly packed.zlib file
- mkisofs creates mountable zlib but no compression
what are the recommended steps to unpack, then pack
and achieve proper unpacking and compression?
is this a known issue in Solaris 11?
root_archive cannot be used to properly manipulate those archives.
The proper way to rebuild media is using the Distribution
Constructor. There's documentation on creating custom media in the
standard doc set.
We could probably be more helpful if we understood what they are
trying to modify in that part of the file system.
