I am not certain that this is absolutely a bug ... but it's very strange
behaviour from FTP, and only happens on our 1.4.2 system (all five 1.4.1
systems are fine):

Here is a snapshot of what happens when you ftp into the system:

ftp foo.motorsport.com
Connected to foo.motorsport.com.
220 montecarlo FTP server (Version: 7.1.0) ready.
Name (foo.motorsport.com:jackd): jack
331 Password required for jack.
Password:
230- NetBSD 1.4.2 (GENERIC) #1: Sat Mar  4 03:08:26 PST 2000
230- 
230- Welcome to NetBSD!
230 User jack logged in.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> pwd
257 "/u/jackjack" is the current directory.
ftp> 

Note the current directory that is displayed!  This is actually still
working: if I list the files, it does display the files in /u/jack
correctly, but it is getting my users very confused.  As far as I have
tested, it happens with all users.

This is on 1.4.2/alpha; I have tested this on 1.4.1/alpha and 1.4.1/x86, and
both are working fine.  I have searched the bug database on netbsd.org, but
to no avail.

Where can I look for misconfiguration?  Or have I stumbled onto a real bug?
