Yes. > And we've long said you shouldn't be doign that :-) Show me the doc or white paper that says so and why. > Not sure install follows that lead.... Okay, let's switch into religious mode. I have long since believe that my /usr filesystem is for all the bits that make the OS work and run. Pretty much everything that is the OS is in there and I like to look at it and say "this needs to be 2GB with Solaris 2.5.1 max." or maybe "this needs to be 6GB for Solaris 10" and once I allocate that space I can easily mount the filesystem read-only or for that matter get completely draconian and stuff /usr into a different disk and jumper it as read-only right on the hardware. That generally means that nothing will get modified, symlinked or messed with until I decide to make a system change. The most ruthless reasons for this are a case where I setup a V880 for someone and they decided that the tools in /usr/bin and /usr/sbin were not nearly as snazzy as the tools from GNU fileutils and binutils etc etc. So they compiled up all this GNU goo and then stuffed them into /usr/bin and /usr/sbin simply overwriting anything that was there. I had a complete fit at the guy that did it and the IT director looked at me like I was a fish and simply said "...we do this with Linux systems all the time. Its called and upgrade." I then told him that I will bill him $300 an hour to fix his problems when they occur. You can only imagine what happened when they went to apply a patch. By the way, that V880 was an important production box for a major tier one car manufacturer in North America and it holds the development version of their web site. So think of all the cars and all the models and all the marketing media and 198 people that worked on those car sections and media etc etc. The sysadmin was a friend of the IT director and he simply did what ever he thought was the right thing to do on Linux. Pure hack and slash. I, on the other hand, try to stick to very draconian ways of ensuring system stability and reasonable performance. All of the Blastwave servers have separate /usr and /var and / and /export/home and /opt. If there is a doc that tells me to do otherwise, I really really want to see that. Dennis
