I recall someone posting that anything in /tmp should not be expected to exist on boot, by programs or user, looking though my /tmp it seems to just be temporary stuff from cron jobs and Firefox, other miscellaneous things as well, I would say it's safe to delete everything in there.

I never really paid much attention to /tmp, but I'm going to start doing that when I remember, I axe everything in /var/tmp/portage every once in a while, though it doesn't get very large; if you do that, make sure you aren't compiling something with emerge, I've done that one before and emerge doesn't know what to do. Also since I run http-replicator for storing packages to distribute to my local machines I also axe /usr/portage/distfiles/ every once in a while. (Typing that sure makes you miss tab completetion in bash)

You should be careful, depending on what you're running. PHP, for example, stores its session data in /tmp, so doing a rm -rf /tmp/* would boot any logged-in users from your server. Also, I think KDE stores UI junk in there too...I notice a lot of folders in there with my username in them whenever I start some KDE apps.
In short, it won't break anything permanently, but it can definitely confuse some programs. |

| One approach would be to check each file/directory in /tmp with fuser and only remove those that have no process using them. |

| It's only safe during bootup. Which is what WIPE_TMP="yes" in /etc/conf.d/bootmisc is for. |

Thanks for that changed to yes for testing.

There is one directory with one file in it in /tmp. I created both of them. I no longer have use for either of them. The only safe way I can delete everything in /tmp is to reboot? |

In that case, you can safely delete them 
Personally, I have loads of other files in /tmp since my last reboot over a week ago, placed there by a variety of apps. I'm surprised that you don't. |
