I think those users will slowly want to move to the newer package
system. IPS provides a lot of additional functionality not found in
SVR4 (to my knowledge):
<long list elided>
Not to mention:
* Automated install of transitive closure of dependency graph.
* Automated detection of package dependencies part of publication
tool chain.
* Manifest signing support that allows cryptographic verification
of all package contents, and supports addition of signatures
to indicate approval for installation in various contexts.
* Faceted packages allow package publishers to provide various
locales, documentation, developer support as part of single package.
Also allows alternate platform support to be elided for
minimization purposes; elided portions of packages are easily
restored.
* Fast enough at generation of packages and update to allow developers
to use native packaging rather than workarounds (bfu & Install);
this should significantly improve packaging quality and reduce
errors.
* Elimination of alternative patching mechanism means no going back
to repatch systems after installation of new packages; added packages
are always correct for current revision level of system.
* Reduction of change stream development costs (no patch scripts to
write!) offers easier opportunity to deliver tailored change streams
to Sun customers.
