mkfs options out of order

[jgreat]

Versions:

• Azure Linux Agent Version:2.2.10
• OS: alpine 3.5.2
• mkfs.ext4: mke2fs 1.43.3 (04-Sep-2016)
• mkfs.xfs: mkfs.xfs version 4.5.0

I'm running the agent in an alpine based container.

I guess mkfs in alpine is picky about the arguments order. Placing the force flag after the device throws an error, which prevents the resource disk from being mounted.
