¿Te quedaste sin espacio en /var?

Pues aqui cuentan como solucionarlo.

Basicamente:

1. stop anything that is using /var where possible
2. remount /var readonly for good measure mount -f -oremount,ro /var
3. copy /var to / under a different name with mkdir /vartmp; cp -av /var/* /vartmp/
4. move things around with mv /var /varmount; mv /vartmp /var
5. comment out the entry for /var in /etc/fstab
6. reboot
