Yes. On second look setting fs->root won't work. We need to change fs.
The problem is that by default all kernel threads share fs so changing
fs->root will have non-local consequences.

I very much believe we want if at all possible to perform a local
modification.

Changing fs isn't all that different from what devtmpfs is doing.
