Ahh, I like yours better. I think in the PR I saw a script called
"writecache" and this will turn off write caching? So the implication
will be that writecache=3DYES will actually turn off write caching?
Umm... Counter intuitive...

Would be nicer if it was a sysctl, but other than that I think your
script is as good as any. Besides, you can choose which disks you want
to do this on too.
