DNS+chroot (Linux): no libraries needed in chroot cell !?!

[Dr. Dorothea Muecke-Herzberg]

Hi there,

has anyone tried to run named chrooted and can help me with my
problems? (running Linux-2.2.6 on a Compaq Proliant1600 and
bind-8.2.1)

First:
I did build named according to INSTALL. (No problems there,
except if I want to build a statically linked version, but that's
another story)

For testing purposes I built a chroot environment without any
libraries
to see which ones are needed and started holelogd (for binding
/jail/dns/root/dev/log to syslogd) and named:
   named -u named -g named -t /jail/dns/root

To my utter surprise named started without any complaint !?! 
Here you see the excerpt of /var/log/messages:

 Jul 21 12:40:42 bastion named[2770]: starting.  named 8.2.1 
 Jul 20 14:50:08 GMT 1999 ^Iroot at bastion:/jail/src/dns/src/bin/named
 Jul 21 12:40:42 bastion named[2770]: hint zone "" (IN) loaded
(serial0)
   .
   .

 Jul 21 12:40:42 bastion named[2771]: user = named
 Jul 21 12:40:42 bastion named[2771]: Ready to answer queries.

First question: What is going on here? Why doesn't named need the
shared libraries?

Second:
My second problem appears 45 min later. See /var/log/messages:

 Jul 21 13:28:02 bastion named[2937]: can't exec /usr/sbin/named-xfer:
 No such file or directory

But there is an named-xfer in /jail/dns/root/usr/sbin (in /usr/sbin
too!)!
According to the above logfile the chroot to /jail/dns/root worked
fine.

Second question: Has someone experienced the same? Can someone tell me
what's wrong?
