[Question] privileged vs SYS_ADMIN in the CSI driver deployment

[lemonlatte]

What did you do? (required. The issue will be closed when not provided.)

I start learning CSI recently. The csi-digitalocean is a pretty good resource for beginners. After study it for a while, I find a question about the privileged in this CSI driver deployment and would like ask for your helps.

When I checked the example in here,

csi-digitalocean/deploy/kubernetes/releases/csi-digitalocean-v2.0.0/driver.yaml

Lines 383 to 385 in a1288db

	privileged: true
	capabilities:
	add: ["SYS_ADMIN"]

I found that it includes both privileged and CAP_SYS_ADMIN.

Doesn't privileged include CAP_SYS_ADMIN? Is there any reason to include both?

Thanks in advance.
