That's fine.... even if you patch only every six months, using IPS is still far faster than fiddling with LU or dropping to single user mode, splitting mirrors, running patchadd and the like.
In contrast. OS installs are a blocking factor. Therefore, it actually does matter how fast they happen, because you cannot do anything with the hardware until the installation process has finished.
I think you'll find that initial OS installs are significantly faster w/ IPS & AI than with jumpstart. About the only thing that's significantly slower is single package install and removal, and if you add the time needed for a human to compute the transitive closure of dependencies, IPS wins there too. Look, we do focus on performance... but optimizing for single package addition and removal on EOL hardware known to be slow for any single-threaded operation is not likely to happen. Pkg install on a T4 or x86 box is perfectly acceptable. There are other areas we need to tune, such as change-facet and the like.
I, for example, have spent WEEKS of time attempting to debug and fine-tune OS installs in the last few months. A faster install process, could have saved me literally days of effort. Guess which case matters the most to *this* customer?
Why not take a system, start with a basic set of packages, and and remove stuff, and then write an AI manifest to duplicate that install? Simple, easy and reasonably fast. If you have lots of systems installing at the same time off the same local repository, be sure to configure Apache front ends, or use NFS repositories for maximum performance. - Bart -- Bart Smaalders Solaris Core OS [email protected] http://blogs.oracle.com/barts "You will contribute more with Mercurial than with Thunderbird."
