For my experiences in the past with OpenLDAP, which keeps its databases by default in /var, I had a lot of inconsistencies triggered due to the port OpenLDAP itself or DB4. I do not care about who caused the inconsistency, but after a reboot, the /var filesystem had to be fsck'ed or was completely trunkated and needed to be reformatted. If this happens to /var when /var is a part of / as a whole, then good night ... ;-) Sorry for the sloppy statement. I'd like to know how many big-company-server systems do have separated partitions and a lucky to have an easy way to repair in compare to home users with their home boxes using a linux like whole one partition ... and compared to that the failures and times to repair the filesystem.
