On another question: what is the rationale behind /usr/tmp anyway? If
/tmp is allowed to be an installable system anyway, why not make /tmp
link to /usr/tmp if it is desirable to keep it on /usr?
Am I missing something?
Yes. The difference is that /tmp is cleared upon reboot (in /etc/rc),
while /usr/tmp usually is not. Therefore, cryptographic materials used
by Kerberos and SPX would be put in /tmp, while editor preserve files
would be placed in /usr/tmp.
Most temporary files should go in /tmp, since they generally aren't
useful after the system reboots. There are some exceptions, though....
