[NTLUG:Discuss] Persistence in /tmp

[Leroy Tennison]

I noticed today that some things I had downloaded days (or months) ago 
continued to exist in /tmp as well as other miscellaneous files.  There 
were a number of PPD files but also downloaded documents, directories 
(empty and not) and socket files.  Most were deletable but some (even 
with "old" dates) weren't.

I was previously under the impression that /tmp was truly temporary 
(cleaned up @ shutdown or restart).  Is that an incorrect understanding 
or am I seeing the results of program bugs in the non-current files and 
directories?
