Russ --- YOU ... are ... SPOOKY How can you remember a date so accurately.
It was Steve who suggested making the root RO and shared. I had only been pushing for shared /usr and things. Sun used to share /usr heavily, as I have said many times, so there is precedent in the non-VM and non-z world, so it should not be a weird idea to other Linux developers, distributors, and customers. But Steve took it up a notch and I am hooked. RPM is (still) the biggest part of the problem. Not RPM per se, but the practices surrounding RPM based packaging. (Same goes for Debian.) As it stands, with a RW and unique /etc for each "client", there will still be some things (that which is in a package which falls under /etc) which won't make it into the shared space and which must be handled. I say this is a small enough percentage. But it is greater than zero. People want to use common tools to manage systems. The majority of tools in the market for managing farms of systems still don't accommodate shared content. They tend to sit on top of unaltered distributor schemes which are designed for single systems each with dedicated disk and their own inventory. This leads to the call for de...de...deduplication (and that's just for the storage recoup and doesn't touch the admin scope creep.) And now I've strayed from Leland's question.
