/tmp is just what its name implies, temporary files.
Nothing in /tmp is needed by the OS across a reboot.
No user files in /tmp are guarenteed to be available
across a reboot. Some admins routinely do a rm -r /tmp/*
early in the boot process. This traditionally is/was
the norm for Solaris.
/proc is totally pseudo. It contains only file pertaining
to currently running processes. After a reboot what value
would it be to know process 1234 "was owned by jon and was
running in the /home/jon directory"? Process 1234 is not
there any longer. Had it died 1 second before shutdown
the files would have existed anyway.
