Just to make sure: This swap.state behavior is only for UFS/AUFS cache_dir or also to rock?

Modification of swap.state upon startup is not incompatible with cache contents preservation. In a clean shutdown context, the swap.state* files are essentially an optimization. You may preserve/restore them if you want to speed up building of the restored cache index OR you can delete them (and Squid will slowly build a new cache index from scratch). Just do not leave the newer swap.state* files when trying to restore the old cache. If you preserve/restore the old swap.state* files, you may need to preserve their timestamps as well. If you need further help, please share cache.log entries related to cache_dir loading and indicate why you think the old cache contents is not preserved. Sharing your cache_dir configuration may also help.
