I'm not sure why folks might have that misguided expectation; Because that's how the default installation has behaved for a long time. I'm not saying this expectation is /wise/; I'm just saying some people have formed that expectation by observing the behavior of the default system, and they would be astonished by this change. > from hier(7): > > /tmp/ temporary files that are not guaranteed to persist across sys- > tem reboots > > Foplks are welcome to do whatever they wish with their own machines, > but the FreeBSD default is as above. Respectfully, no. The default is to store /tmp in UFS, either in its own partition (with Auto Defaults) or in / (if no partition was created for it), and to refrain from clearing it at boot. Thus, although /tmp is not guaranteed to persist in theory, it is rather persistent in practice. My only point is: carefully consider the change in behavior of the default installation before breaking the POLA. EricReceived on Thu Mar 29 2012 - 18:53:25 UTC
