I would agree that setting the root shell is a dangerous thing as there could be code run at boot that assumes the shell has not been changed. It should run the code that calls in the /sbin/init.d scripts with a sh call, but will that calling script work in bash is another question. You would have to check so much that it's probably not worth it and any patches might undo any adjustments you may have to make.
Could I suggest that you don't login as root directly anyway. Unless this is only ever going to be a personal system, there is a likelihood that you will need to share the password at some point.
A more controlled/audit-able way is to log in as a standard user and use su to become the root user. If you have sudo privileges, then it's even easier. You could put a one-line script in your path similar to this:-
Code:
sudo su - root -s /bin/bash
I would consider preventing root login except from the console, both for telnet and SSH connections. Change and secure the root password and have that only used in a dire emergency.

libbash
LIBBASH(7) libbash Manual LIBBASH(7)NAME
libbash -- A bash shared libraries package.
DESCRIPTION
libbash is a package that enables bash dynamic-like shared libraries. Actually its a tool for managing bash scripts whose functions you may
want to load and use in scripts of your own.
It contains a 'dynamic loader' for the shared libraries ( ldbash(1)), a configuration tool (ldbashconfig(8)), and some libraries.
Using ldbash(1) you are able to load loadable bash libraries, such as getopts(1) and hashstash(1). A bash shared library that can be loaded
using
ldbash(1) must answer 4 requirments:
1. It must be installed in $LIBBASH_PREFIX/lib/bash (default is /usr/lib/bash).
2. It must contain a line that begins with '#EXPORT='. That line will contain (after the '=') a list of functions that the library
exports. I.e. all the function that will be usable after loading that library will be listed in that line.
3. It must contain a line that begins with '#REQUIRE='. That line will contain (after the '=') a list of bash libraries that are
required for our library. I.e. every bash library that is in use in our bash library must be listed there.
4. The library must be listed (For more information, see ldbashconfig(8)).
Basic guidelines for writing library of your own:
1. Be aware, that your library will be actually sourced. So, basically, it should contain (i.e define) only functions.
2. Try to declare all variables intended for internal use as local.
3. Global variables and functions that are intended for internal use (i.e are not defined in '#EXPORT=') should begin with:
__<library_name>_
For example, internal function myfoosort of hashstash library should be named as
__hashstash_myfoosort
This helps to avoid conflicts in global name space when using libraries that come from different vendors.
4. See html manual for full version of this guide.
