Description Erik Damrose

ucc-base sets two sysctl values on a thinclient: 
/proc/sys/vm/dirty_expire_centisecs
/proc/sys/vm/dirty_writeback_centisecs
After normal system boot dirty_writeback_centisecs is however set to its default value 500. If the upstart script is called manually, the value is set back to 10.

We should set this in a LightDM session setup script.

The configuration of the writeback settings has been moved into the session setup script, which already tightens the permissions of /run/drives.

The writeback settings are set to the correct values after a succesful login -> OK

-> Verified
