Not really what is being ask, but SUN invented /var to hold the things that were on /usr that couldn't be shared. This is why it is so hard to share /var. If there is something on /var that should be shared then it should be moved to /usr.

Sun set a precedent for sharing /usr more than a decade ago. Linux has been slow to pick-up on the idea (because most Linux systems are on independent PC class machines). Sun uses NFS. Now with zSeries Linux running on VM, there is physical (appears to Linux) sharing of the underlying device, which Sun did not have. Now with SAN, Sun can enjoy sharing physical devices too! For that matter, non-mainframe Linux can share volumes (on SAN). /usr and /opt are the most immediately obvious choices. The root can be difficult, but your /etc and /var content are even more difficult than a shared root FS. (/boot is generally sharable if you split it from the root; I do.) -- 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 ---------------------------------------------------------------------- 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
