hi, Craig,
thanks for the excellent bug report.

I can reproduce the problem with sysklogd... I based the debian init
script on the redhat one provided in the unbound tarball, which
bindmounts /dev/log to /var/lib/unbound/dev/log. unfortunately since
/dev/log is a unix socket, it disappears and is recreated when the
syslog daemon is restarted, and the bindmount follows the inode rather
than the directory path.
just to verify, could you send the output of `stat /dev/log
/var/lib/unbound/dev/log | grep Inode` before and after a restart of
unbound? it probably looks something like this:
[EMAIL PROTECTED]:~# stat /dev/log /var/lib/unbound/dev/log | grep Inode
Device: eh/14d Inode: 7916330 Links: 1
Device: eh/14d Inode: 2945675 Links: 0
[EMAIL PROTECTED]:~# /etc/init.d/unbound restart
Restarting recursive DNS server: unbound.
[EMAIL PROTECTED]:~# stat /dev/log /var/lib/unbound/dev/log | grep Inode
Device: eh/14d Inode: 7916330 Links: 1
Device: eh/14d Inode: 7916330 Links: 1
[EMAIL PROTECTED]:~#
now, could you please test this solution?
1) /etc/init.d/unbound stop
2) echo "$AddUnixListenSocket /var/lib/unbound/dev/log" >
/etc/rsyslog.d/unbound.conf
3) /etc/init.d/rsyslog restart
4) replace /etc/init.d/unbound with the copy attached to this mail
5) /etc/init.d/unbound start
