[Bug 223825] Re: aiccu init.d script will race dhclient (upstart issue?)

[Chris Halse Rogers]

I've fixed a couple of things in the debdiff and uploaded it.  Specifically:
*) I mentioned what the purpose in transitioning to an upstart script was in the changelog
*) I retargetted the changelog entry at Precise, the current development release
*) I dropped the debian/aiccu.maintscript addition; dh_installinit handles the removal of /etc/init.d/aiccu itself.

Thanks for your work!

Title:
  aiccu init.d script will race dhclient (upstart issue?)

Status in “aiccu” package in Ubuntu:
  Fix Released
Status in “aiccu” source package in Karmic:
  Won't Fix

Bug description:
  Binary package hint: aiccu

  aiccu comes with a SysV-style init script.  In the dark ages before
  upstart (and before NetworkManager?) this worked fine with a link from
  /etc/rc2.d/S99aiccu, but ever since, there's a race for DHCP users:
  aiccu won't sit around waiting if it can't reach the tunnel broker,
  and DHCP configuration happens late, after aiccu terminates.

  Observe this snippet of syslog produced at boot (Hardy / 8.04):

  When I have a moment I'll figure out an upstart script for it, this is
  just to document the issue.
