man fakeroot

when you do something like mknod(1) which usually requires superuser
permissions, what fakeroot does, is to actually create a normal file (it
doesnt have the priviliges to create a real device node) and keep track
of this file as a fake device node.

so as long as you are within the fakeroot call every application will
see as a device node whatever you created with mknod. While outside of
it, it is just a normal file.

as said, above, for more information read the manpage.

cheers, josch
