I also have /tmp as a tmpfs mount and my concern, in addition to
vi.recover, is that the upgrade guide for 5.6 explicitly mentions
backups of files replaced by sysmerge surviving a reboot in /var/tmp
(at least for a few days). What will happen in 5.7?

The commit message says that some daemons assume they will not run out
of space in /var. Which ones? That seems like a really bad assumption.
