[Xen-tools] [RFC] Daemon startup order

[Anthony Liguori <aliguori@xxxxxxxxxx>]

Hi,

A few people are having problems with the new console daemon and I've 
tracked the problem down to the order in which daemons are started.  
Here's what currently happens:
1) xend (the script in tools/misc) start will launch xcs and consoled
2) xend (the python server) will launch xenstored whenever it needs it

This creates a bit of a chicken and the egg problem since consoled needs 
xenstored to function.  There's a few options:
1) Have consoled (and all future daemons) implement the logic to wait 
for xenstored to start
2) Move xenstored launching to xend (the script in tools/misc)
3) Give all the daemons proper init.d scripts with dependencies

I'm partial to #3 although #2 would be a fine quick hack.

For now, if anyone gets messages about not being able to read the tty 
with xm console, simply run consoled.
Regards,

Anthony Liguori
