I'm setting up a new Linode server and following steps from here: https://help.ubuntu.com/community/StricterDefaults
2 times now if I follow the following steps:
Edit /etc/fstab Add this line: tmpfs /dev/shm tmpfs defaults,ro 0 0 Reboot
After reboot I'm no longer able to ssh into the server.
In /etc/fstab, its indicated in the format comment that the file path should be the first option. "tmpfs" is before that. Could this be a typo in the documentation?
