[Bug 839595] Re: failsafe.conf's 30 second time out is too low

[Leo Milano]

@ Scott: thanks for the detailed response. It all makes sense now. I am
guessing perhaps wicd wrote that entry in my interfaces  file. I haven't
edited this file by hand.

@ Clint: yes, I think it makes sense to add this to the release notes.
Thanks for updating the description. It seems like this is a reasonable
approach for now.

Longer term, I think the start system needs more granularity. Ideally,
if the network is still not up, most services (except for things like
ntp, firewalls, etc) should start anyway. The user should still be able
to get X up and running, and be able to login. But the current structure
of one upstart hook to all sysvinit services won't allow for that.

Thank you for the great work, and I hope this little extra bit of info
benefits other users.

Best!

Title:
  failsafe.conf's 30 second time out is too low

Status in Release Notes for Ubuntu:
  New
Status in “upstart” package in Ubuntu:
  Fix Released

Bug description:
  **** RELEASE NOTES ****

  If a system has network interfaces defined in /etc/network/interfaces
  as "auto", the operating system will wait up to 120 seconds for those
  interfaces to be fully detected and configured before continuing to
  boot the system. Most users of Ubuntu will not be affected by this
  change, as only servers and dedicated workstations should have network
  interfaces configured in this way.

  ************************

  as far as I can understand, the 30 second sleep in failsafe.conf means
  that /etc/init/rc-sysinit.conf will start within at most 30 seconds of
  'filesystem' and 'ifup lo' having occurred.

  I think that is really to small a number.   You're only safeguarding
  against the case where a user had an entry in /etc/network/interfaces
  that where the device was removed or is not connected.  Thats a very
  rare case.  Increasing the timeout to 60 seconds would make it less
  likely to have a false positive and have rc-sysinit start early.  (Ie,
  the case where a dhcp took 35 seconds).

  The user will only be punished by waiting an additional 30 seconds in
  the case that they have a  misconfigured or out of date
  /etc/network/interfaces.
