I do not really understand what you suggest. Is it to replace the
'exit 0' by 'exit_with_hooks 0' in
etc/dhcp3/dhclient-exit-hooks.d/dhcdbd ?
If I correctly read the code, dhclient executes /sbin/dhclient-script.
At the end of this script, there is a call to 'exit_with_hooks 0'
In this function, dhclient-script sources one after the other all the
files in /etc/dhcp3/dhclient-exit-hooks.d/
The problem is that /etc/dhcp3/dhclient-exit-hooks.d/dhcdbd calls
'exit 0' so /sbin/dhclient-script exits immediately without sourcing
the other scripts in /etc/dhcp3/dhclient-exit-hooks.d/
I do not understand why this 'exit 0' is needed. It is not documented
and makes the dhcp script system behave very strangely. Some scripts are
executed, and others are not.
And I do not think that calling 'exit_with_hooks 0' instead of
'exit 0' will work: there will be infinite recursion (but I do not test
it, yet)

Vincent
