[Pkg-sysvinit-devel] Bug#461461: sysv-rc: ntp brought up in wrong order with dhcp and ipv6 enabled

[Rick Thomas]

Package: sysv-rc
Version: 2.86.ds1-47
Severity: important


On a system with ipv6 networking enabled and the IPv4 dhclient installed, ntp is brought up before the network 
interfaces are ready for it.  The result is that the ntpd daemon is unable to contact any servers and cannot 
synchronize.

Relevant parts of syslog are included below
