The combination is neither ideal nor fully supported today IIRC. The ideal would be just your second part -- change squid.conf and run "squid -k reconfigure". The first part (i.e., a dedicated "squid -z" run concurrent with the primary Squid instance) is not ideal for many reasons that I do not have time to detail here (but you may be able to find some relevant references by searching for -z in Bugzilla and squid-dev archives). We need to start supporting cache_dir initialization dynamically, but nobody is working on that difficult project right now AFAIK. As for "how later?", a correct implementation should probably remove the old cache_dir when it is no longer used by any process. That check is going to be OS- and possibly fs-specific. Squid could also log a message when it stops using a removed cache_dir, but I am not sure that polling for such messages is a better approach -- what if Squid crashes before emitting that message, for example?
