[COLUG] Linux Startup Sequence

[Steve Roggenkamp]

It may take a while for VMware to get to the point where it has started 
and configured the network interfaces.  Not knowing the details of your 
setup I would venture the following events:

- S90vmware starts a VM and initiates the boot process.  It puts the 
process in the background and returns.
- S91postgresql-8.1 starts but the VMware process has not completed the 
network configuration and it fails
- Time passes and the boot sequence completes.
- You login, perhaps muttering innuendos about the computer's ancestry
- By this time VMware has completed its network configuration
- You type in the command to start postgresql and it works

I would suggest putting in a

    sleep nn

Where nn is a number of seconds to delay into the S91postgresql-8.1 
startup script before it actually starts the service.

You might want to make nn something like 30 initially, then cut it down 
to something less as you find out how long it will take VMware to 
configure the network.
