Only if you are taking a portion of the current UFS cache and giving it
to COSS (not a good idea to have 2+ cache on same disk anyway).

To simply change the existing UFS cache to AUFS and add a new disk for
COSS all you need is this:

  * partition/format COSS disk
  * configure new coss cache_dir in squid.conf
  * change ufs tag to aufs in squid.conf
  * stop squid
  * run squid -z
  * restart squid

NP: I only bother stopping to be 100% certain the change to aufs does
not make the -z alter anything in active use. It is probably only a -z
then reconfigure needed.
