Not trying to start a flame war here, but we can actually go a step
further.
Traditionally, an empty shell field in /etc/passwd has meant that /bin/sh
is the user's shell.
We can use that tradition to make the choice of shell more friendly.
Here's the idea:
1. When new accounts are created, default to an empty shell field in
their passwd file entry;
2. Modify the default /etc/profile so that it checks to see if the
shell field is empty or not. If it is empty, present the user with
a list of shells obtained from /etc/shells and ask them which one
they want to use. Default to the shell saved in adduser.conf if
nothing is entered, or /bin/csh if adduser.conf doesn't exist.
3. Based on their choice, run "chpass -s" to set the user's shell to
whatever it is that they've wanted.
4. Tell the user that they'll now need to login again, then exit. Next
time they login the test in (2) will see that the shell field is
non-empty, and won't ask any stupid questions.
That means the user is asked about which shell they want when they login
for the first time, after that they won't be bothered again. Note that
this only affects actual logins, because it'd be done out of /etc/profile,
so most role accounts (which are typically accessed via "su", not via a
login session) would continue to work in the same way they've always worked,
but accounts which are actually used for real-live login sessions can
be customized by the user when they login for the first time. Furthermore,
if a site wishes to standardize on a certain shell, or if the sysadmin
who sets up someone's account already knows their preference, that's ok too:
the shell field can be preinitialized with whatever is supposed to go there.
Note that this means that most current practices will remain unchanged;
the only real change is that accounts with unspecified shells present a
menu upon the first login (but not the first "su"). The only file which
needs to be updated to achieve this outcome is /etc/profile.

For people who don't know about the chpass command, yes. So turn it
into a "choose from the following options..." style of menu.
