The first time I tried to boot a system using files from the temp 
rootfs, I quickly found that some parts were missing, like all the /dev 
nodes, due to permissions when constructing the rootfs if I recall 
correctly.

That was a while ago so maybe things are different now, but I'm glad 
that the "wrong" files are removed now to reduce (my) confusion.
