However, if you always want to use tmpfs instead of stable storage,

please do not.  Some people expect /tmp to be persistent.  This is why /etc/defaults/rc.conf has clear_tmp_enable="NO".  Changing this would break the POLA.

This is a mistake.

The default should be clear_tmp_enable="YES" if only to uncover those broken configurations that expect /tmp to be persistent.

If you want to break POLA and make a lot of people angry, sure. Otherwise no.

I couldn't agree more. Not clearing /tmp on reboot has been the norm for way too long and it is too late to change now. It's not just POLA, it also involves deleting data of unaware users, and that should be avoided.

Anyone willing to change policy w.r.t. /tmp can do so on their own machines. Nothing is preventing them from doing so. But by changing defaults, one should err on the side of caution and remain conservative, IMHO.

Well stated.

From man hier:

/tmp/ temporary files that are not guaranteed to persist across system reboots

There is also a difference between "not guaranteed to persist" and knowingly blowing the files away by explictly clearing /tmp.

PS: How many users of FreeBSD know that hier(7) exists? How many new users even know about man pages?
