Running inside a chroot

[Paul Whittaker]

Hello,

I'm looking for some help getting mathopd to serve pages when it's
running inside a chroot using the RootDirectory config option.

On the surface everything is ok: it doesn't print any errors at
startup, and there's nothing obviously wrong when I look at the log
files or run the server via the strace command.  The log files are
also being correctly constructed inside the chroot, and are written to
when I make requests for pages.

The problem is that I seem only to be able to get "500 Internal Server
Error" responses back when I ask for a page!

If anyone can spot what I'm doing wrong, or (perhaps easier) post a
working mathopd.conf that includes a RootDirectory setting, that would
be great.

Many thanks in advance,

Paul.
