[Desktop-packages] [Bug 1332947] [NEW] unity randomly turns on large text in universal access

[mkovac]

Public bug reported:

I have a macbook pro with retina display. In Ubuntu 14.04 64bit, every
couple of reboots, the 'large text' option in Universal Access gets
switched on upon login. It happens in roughly 1 out of 5 reboots for 1
or more users on the computer.

It appears to happen to people with small HighDPI screens. In my case, it's 13 
inch at 2560x1600.
Another example is 13 inch at 1080p -

[Desktop-packages] [Bug 1157332] Re: /etc/dnsmasq.d-available/lxc circular link

[mkovac]

I've just installed lxc (0.8.0~rc1-4ubuntu39.12.10.2~ubuntu12.04.1) from
precise-backports and got the same circular link warning. Will the
package in backports get fixed?

Bug description:
  = Rational =
  We pushed a custom dnsmasq hook to precise, quantal and raring over the past 
few months to avoid conflicts for people running the dnsmasq system daemon 
(non-default).
  However because we introduced this change as SRU, it's causing problems when 
then upgrading to the next release by having the migration code get executed 
multiple times.
  We need to fix this and repare broken systems in the process.

  = Test case =
   - Install any of the current  lxc, libvirt-bin or network-manager on Ubuntu 
12.04 or 12.10
   - Dist-upgrade to the next version of Ubuntu
   - You'll notice /etc/dnsmasq.d-available/FILE is now a circular link, 
/etc/dnsmasq.d/FILE no longer exists and the old content is moved to 
/etc/dnsmasq.d-available/FILE.dpkg-new (where FILE is lxc, dnsmasq or 
network-manager)
   - Updating to a fixed package will move everything back into place (assuming 
the user hasn't done any local change in between, in which case, nothing will 
be done)

  = Regression potential =
  I have tested the change doing precise -> quantal -> raring and quantal -> 
raring and I'm confident the new postinst hook will fix any breakage. It's also 
specific enough to only trigger in the specific case we know how to repair. In 
all other cases, we keep the system as-is and let the user deal with it. As a 
result, it's not impossible that some weird corner cases (for example when 
removing/purging the package in between dist-upgrades) may go unfixed but I'm 
confident we'll cover at least 99% of the cases with the fix and that this fix 
is safe.
