<p>It's safe to put both of these in tmpfs, and since they're fairly busy
it's a good idea for performance reasons. Further, nothing ever removes
files from <configdirectory>/lock/, so it's probably a good idea in
general to mount that on tmpfs such that a reboot will purge it. The
Cyrus code will create all the necessary directory structure under
<configdirectory>/lock on-demand.</p>
