I would personally not use bash for a root shell. This is because it
usually sits in the /usr partition. I want root to be able to run a shell
even if the /usr partition gets corrupted - so I stick with /bin/csh. 
(Actually, the first thing I do as root is usually type exec 
/usr/pkg/bin/bash, but that's another story...)

My advice is: DON'T DO ANYTHING ABOUT THIS. Stick with /bin/csh.

This is usually done in your personal .bashrc and/or .bash_profile files.
See "man bash" (i.e. type man bash in a shell on your machine).

Primarily, use the man pages: e.g. "man inetd.conf" will tell you about the
program inetd and its configuration file.

Second, see the NetBSD website - useful for Frequently Asked Questions and
the like.

If you understand Italian, there is a getting started guide in Italian 
(hopefully this will be translated into English very soon) written for
NetBSD - more details at www.netbsd.org.

When you have been using the system for a bit, read the UNIX 
System Admin. Handbook. This is not a beginner's book, but
it has a lot of information in it.

HTH; best wishes,
