guest session leaves cruft behind

[Rolf Leggewie]

I'm not sure this is a bug in unity-greeter, most likely it is another component.

After using the guest session feature (log in as guest) a couple of times I find the following cruft on my system. This shouldn't happen.

$ grep guest /etc/shadow
guest-ceyM7L:*:15982:0:99999:7:::
guest-Qb2HtL:*:15989:0:99999:7:::
guest-9KbZAI:*:15995:0:99999:7:::
guest-Jz5Iz0:*:16011:0:99999:7:::
guest-kWc1MQ:*:16014:0:99999:7:::
guest-iqcR95:*:16026:0:99999:7:::
guest-5UTOnm:*:16082:0:99999:7:::
guest-iXkNz7:*:16101:0:99999:7:::
guest-nHX8MC:*:16502:0:99999:7:::

guest-y5JvoT:*:16756:0:99999:7:::
guest-YBXQ1O:*:16762:0:99999:7:::
guest-d2N35B:*:17043:0:99999:7:::
guest-B222qB:*:17073:0:99999:7:::
guest-B4IqVx:*:17110:0:99999:7:::
guest-51gqiH:*:17142:0:99999:7:::

Other files seem to be affected as well.

$ sudo rgrep -l guest-ceyM7L /etc/
/etc/group-
/etc/group.org
/etc/gshadow-
/etc/passwd-
/etc/passwd.org
/etc/shadow-
/etc/shadow.org
/etc/group
/etc/gshadow
/etc/shadow
/etc/passwd

I'm running unity-greeter 14.04.11-0ubuntu1 on trusty.
