Does your system have something like an nsswitch.conf where "passwd: files"
or similar would need to be specified? I don't use FreeBSD and don't know
if it's an nsswitch.conf type system, but if not then it probably has some
similar configuration file.
-) I do get funny characters printed when typing a backspce, hitting
delete or entering CTRL-D to exit the shell.
Psuedo-terminal settings. Maybe /etc/profile (or similar) has some
terminal behavior commands (like stty) that didn't get copied into your
chroot area.
I assume both observations are connected to each other.
I don't think so. Unless you mean they're both connected by missing
configuration files for their respective areas.
What am I missing
here to build a minimal but fully functional environment? Any comments
are
greatly appreciated. Dave.
Just build it one piece at a time until it works for what you need it to
do, and then document what you included an why it was included (for next
time). Read the man pages of things that don't work yet to figure out what
configuration files and other binaries they need. Use ldd to find
libraries your binaries use, and learn about how those libraries work and
if they too have configuration files that you need to copy over (like
nsswitch.conf). Then you'll have the perfect chroot jail for your
application.
There's probably no magic bullet answer to cover every situation.
