Won't there be any kernel cache, so `sync` command is their for coping
with the cache?
I'm not sure what you're asking. Unless you tell it to write
synchronously, "dd" will use the kernel caching as normal. But it also
does a sync at the end, so it won't actually exit until everything is
written. There's no need to run "sync" after. If you use the progress
option, you'll see that it has "written" all the data, but it's still
quite a while after that before it exits.
