Add a "varshm" check/fix to make sure /var/shm is mentioned in /etc/fstab 

(and add a default of tmpfs with 25% of available ram limit if not).
To avoid the warning but not mount the tmpfs, just comment out the line
for /var/shm.

Also move "obsolete" to the end of the list again, as it should be run
last.
