Show Suggested Answer

Suggested Answer: D, E

n Oracle Solaris 11, you can use the deduplication (dedup) property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored, and common components are shared between files.

Okay, so shutdown is the boss and init is the intern. Got it. I'm gonna remember that during the exam.

Hah, imagine if init was like 'Alright, I'm out. Figure it out yourselves!' That would be a mess.

But init is needed to shut the system down to run level 0, right?

Yes, that's true. Shutdown also sends a message to systems mounting resources.

I think the main difference is that shutdown broadcasts a final warning to all users.

I'm not sure about the single-user milestone thing, but the power-off option with shutdown is pretty neat. init just quits, how boring.

The shutdown command seems to have more features than init, like broadcasting warnings and shutting down mounters. I like the cleaner shutdown of services too.
