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...
I don't really follow how this works. Seems like a Goldberg-esque
contraption from this description.
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?
Literally *anything* can be done in DC, so that makes no sense. One
might end up writing specific custom checkpoints for some more complex
things, but the means to do that is documented and certainly well within
the capabilities of ISV's such as this.
Anyway, the .zlib archives are compressed using lofiadm -C.
they used "root_archive pack / unpack" on Solaris 10 but
those options appear to be removed on Solaris 11...
Yes, they are, as the Solaris 11 media architecture is very different
from Solaris 10.
Dave
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.
