Yes I have seen that and didn't had time to send you a note about it yet.

Since rock is a new type and squid -z reset it even if it's OK.
I think that like in ufs case squid -z should not reset the rock store
file and just recreate it if it's not there.
The reason is to be consistent with ufs and also prevent this kind of
problem.

This should be files as a separated bug.

what I did to CentOS init script is to start with:

CACHE_AUFS_SWAP=`sed -e 's/#.*//g' $SQUID_CONF | \
         egrep "^cache_dir (auf|ufs)"| awk '{ print $3 }'`
CACHE_ROCK_SWAP=`sed -e 's/#.*//g' $SQUID_CONF | \
         grep "^cache_dir rock"| awk '{ print $3 }'`

And later check a dir or file existence by the store.

This helps the init script to prevent false identification of cache_dir
but not preventing the very wrong squid -z action.
