Right.. hostfs will almost certainly not work well with file mode 0
until the virtual permissions layer is implemented.
Today hostfs directly maps permissions to the host files, which breaks
root semantics for UML. Normally root expects that mode does not matter
when reading/writing files, but when using hostfs it does matter when
UML accesses the host.
