Increase default /dev/shm size

Summary

Is there currently a configuration value for increasing the default /dev/shm size?

I have been debugging this issue with the chrome-mink-extension and one part of the fix is giving Chrome more shared memory to work with. I am able to do this via the cli, but is there (or could there be) a configuration value that will provide a higher shared memory allotment?

For anyone wondering how to increase this value manually, FWIW I took the route mentioned here.

I can't think of any built in way of doing this... do you just need more space on the system volume?

@geerlingguy I can try that out, I'm not sure if it would make any difference. Is there a configuration option for this?

[geerlingguy]

Not really, the easiest thing would probably be to create your own base box with a larger default size. Drupal VM's main drive in the geerlingguy/* base boxes is capped at like 80 GB currently, but I don't do any other volume configuration.

See related:

• Add some way to increase disk space from Vagrantfile hashicorp/vagrant#2339
• https://github.com/sprotheroe/vagrant-disksize

Not sure if anything in there will help with /dev/shm directly though. Can you configure the chrome-mink-extension to use storage other than /dev/shm?

Closing this for now, as I don't think there's anything simple I could do to make it easier to configure via Drupal VM/Vagrant without resorting to a bunch of Ansible tasks that I'd rather not have to maintain for multiple OSes.
