Yes, this seems correct. I will not that you CAN NOT use mapcache_seed 
AND web requests TOGETHER as they do not use compatible locking 
mechanisms. So either use mapcache_seed before you deploy or use the web 
requests to dynamically seed the cache. You can use mapcache_seed to do 
a partial pre seeding (like rectangles around major cities) then change 
over to web request which will generate tiles as needed in the remaining 
areas.
