First, I must apologize for the previous mangled message.  I
keep forgetting that this is one of 2 lists I am on that don't
seem to like the MIME encapsulation my user agent generates. if
I bypass the mime encoding and go directly to sendmail, all is

	I want to run dhcpd in a chroot environment under
FreeBSD6.2.  The top of the tree is 
/usr/local/chroot/dhcpd.  In there is:


Under usr/local is /etc for the configuration file.  A listing
of the dev directory under dhcpd is as follows:

total 0
crw-------  1 root  wheel    0,  94 Mar  9 15:24 bpf0
crw-------  1 root  wheel    1,  95 Mar  9 15:24 bpf1
crw-rw-rw-  1 root  sys      2,   2 Mar  9 15:24 null

	When I start dhcpd in chroot, it looks like it is going
to run.  One sees the copyright message, the normal warning

WARNING: Host declarations are global.  They are not limited to the scope you declared them in.

and it starts to run.

Wrote 0 deleted host decls to leases file.
Wrote 0 new dynamic host decls to leases file.
Wrote 0 leases to leases file.

and then this show-stopper.

No bpf devices.   Please read the README section for your operating system.

	Since it works when run as root, I must have something
either in the wrong place or there is something missing from the
chroot environment.  Are there any ideas as to why I get this
error.  I think there is a nice bpf device there that looks just
like the listing of /dev/bpf and /dev/bpf1 but obviously
something isn't right with the chroot version of things.

	Thanks for any help.  The man page on bpf doesn't tell
me anything that has started any investigation.
