Here comes a new udev version. Thanks to all who have contributed to
this release.

udev 155
====
Bugfixes.

Now the udev daemon itself does on startup:
  - copy the content of /lib/udev/devices to /dev
  - create the standard symlinks like /dev/std{in,out,err},
    /dev/core, /dev/fd, ...
  - use static node information provided by kernel modules
    and creates these nodes to allow module on-demand loading
  - possibly apply permissions to all static nodes from udev
    rules which are annotated to match a static node

The default mode for a device node is 0600 now to match the kernel
created devtmpfs defaults. If GROUP= is specified and no MODE= is
given the default will be 0660.

Looks like /dev/fd is pointing at /proc/fd.  I think this should be
/proc/self/fd (unless newer kernels added /proc/fd).  Trivial patch follows.

Yeah, that should be "self". Applied.

Thanks,
