Please use spaces rather than tabs ;-)

Hm, I didn't look carefully, but won't this break if you have a folder
named, say, "/mnt_1"? I suppose you could use some unused escape code
similarly to how '/' is encoded?

How are you making sure that the mounts are stacked in the right
order? You'd want to order mounts that are 'higher' in the stack
After= the mounts that are lower down (in the same way as home.mount
is now ordered After=-.mount).

Use 'git send-email', that way people can comment inline (and you
avoid linke-break problems that usually results from pasting the patch
into your email client).
