Once again the process of applying an update takes up a disproportionate amount of disk space.
Even with app.update.staging.enabled set to false I observed it consuming around 220MiB.
(I believe it takes up even more when this is set to true).
If it runs out of space before it's done applying the update, it breaks TBB completely ('3817 Bus error' on line 368 of Browser/start-tor-browser).
Maybe having staging.enabled set to true prevents the breakage, but I don't have enough disk space to apply updates that way (uses something ridiculous like 400-500MiB).
Anything you can do to apply updates in a way which doesn't use all the disk space at once would be great.
