[Bug 932598] Re: Full hard drive causes xorg and lightdm to fail to load

[Martin Pitt]

There are two parts to this:

 - Somewhere in the upstartification we lost the emergency mounting of
an 1 MB /tmp tmpfs if /tmp had less than 1 MB of free space. This is in
mountall, I'm working on this.

- lightdm cannot write /var/lib/lightdm/.Xauthority as user "lightdm"
when the disk has less than 5% free space (i. e. it counts as "full" for
users). Here it would help if lightdm wrote its .Xauthority file
somewhere into /run/. Robert, does it actually need to be permanent
across reboots?
