Yes, I think so. But you didn't mention how you switch to runlevel 5. Is 
it done from one of your init scripts or is it done manually?

/etc/bash.bashrc has nothing to do with init scripts. The first line of 
that file is this:

# System-wide .bashrc file for interactive bash(1) shells.

It is _only_ used for interactive shells but those init scripts are not 
interactive login sessions. An interactive shell is what you get when 
you enter your login and password at a terminal.

What do you mean with "when I a user logs in to run level 5"? Again, you 
didn't mention how you switch to runlevel 5. Unless you do that manually 
or by one of your init scripts, that never happens automatically on a 
Debian or Debian derived system like Ubuntu.

1) It has nothing to do with runlevels (see above).
2) It is included by /etc/profile but only for interactive shells. 

Anyway, talking about bashrc is only misleading when you want to run 
daemons which are invoked by init scripts because there is no 
interactive shell involved. And as I understand this thread, that is 
what you want to do. If you really want to include /etc/bash.bashrc in 
your init script you can do it with a line

. /etc/bash.bashrc

somewhere in your script before you need the variables set by 
/etc/bash.bashrc. However I'd rather copy the needed lines from that 
file to your init script.
