Comment 4 for bug 2019026

> how would it impact you if it was NOT cleaned at reboot?

I just like it. It's easier for me to keep track in my head that "oh, this file in /tmp will only be around until I reboot", as opposed to trying to keep track of the actual age of a file. To be clear, I am not suggesting that my use case is strong argument for keeping the current default (I will happily write an /etc/tmpfiles.d/tmp.conf drop-in to meet my preference if needed). Just pointing out that there might be a range of preferences on the default handling of /tmp.

Also, you may have already come across this, but if not, this is the Debian bug that resulted in the current default: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=675422.

If you think it would be best for most Ubuntu users to change the current default, then we should go with your suggested change. If the motivation is mostly about your schroot use case, then I would suggest either modifying schroot to do what you need, or using /etc/tmpfiles.d/tmp.conf.
