Title: Pull video ephemeral dir fix (#942) into master

Tested:

1. end-to-end test against staging: uploading video works, watched /mnt and saw the file created there. Note that I didn't see it get removed right away, but I don't believe that is related to this change.

2. used deploy.dev to ensure that permissions on /mnt survive a reboot. This is important since most of our machines are micros, where /mnt is just a directory, and on the smalls /mnt is a mountpoint for a different disk. And while that *shouldn't* matter for dir perms, worth double checking to make sure.
