Robert, in my experience (and from non-Linux precedent from years ago) it's much easier to share filesystems like /usr and /opt. Rob mentioned that in painfully too many cases "only part of the code is shared and some is not", so even for these two filesystems you're not always going to cover all files that might be in any given RPM. You will have to be aware. In practice, I share /usr read-only among several zSeries penguins. These instances are VERY stable in so far as they don't change much. And I've done a lot of manual twiddling to reduce what is in /bin (moving things carefully to /usr/bin). Likewise for /lib. My advice: do it! Require support for it of your Linux distributor. Require sharing tolerance from your various package vendors. You will NOT immediately recognize a lot of disk savings (and disk is cheap), but in time. You will not immediately recognize sysadmin time savings, but that too in time. But you will have to ramp up on the curve before you recognize any return on this investment. -- R; ---------------------------------------------------------------------- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390
