If you run multiple servers of any kind, the second and subsequent servers must have a command line switch specifying the location of the config file. This is the way named, sendmail, et al do it. I have run multiple nameds on a single box, by using alternate config file locations. > 2.

Or you specify the default location with a configure switch at compile time. Or you do it the same way you would run any other typical daemon as a regular user. How does Apache, AOLserver (my favorite), sendmail, jabberd, named, or any other typical daemon do it? For example, AOLserver can easily be installed and run as a plain user (just not on port 80). The command line switch '-t' specifies the tcl configuration script's location. There is no default. The configuration script then specifies pageroot and the like -- and a webserver is very much like running PostgreSQL -- you have configuration, you have logs, and you have the spool (database or pageroot). All can be in different locations at the discretion of the admin. And hardcoding dependencies like this stifles the discretion of the admin. > These conditions have both been known to occur... Just because the situation is known to occur doesn't mean the whole direction of a project should hinge on those corner cases. They should be allowed but not forced. For better or for worse, thanks to Karl DeBisschop, the latest RPMs have the ability to start multiple postmasters with their data trees and configurations in different places. This is all done in the startup script, and required no new functionality from postmaster. I personally think it is for the better; YMMV. -- Lamar Owen WGCR Internet Radio 1 Peter 4:11 ---------------------------(end of broadcast)--------------------------- TIP 1: subscribe and unsubscribe commands go to [EMAIL PROTECTED]
