Description of problem:

This isn't a dracut bug, I'm just assigning it to
dracut because usrmove/convertfs caused the breakage.

$ touch test.x
$ rpcgen -h test.x
cannot find any C preprocessor (cpp)
[...]

It turns out that /lib/cpp symlink is broken:

$ ll /lib/cpp
lrwxrwxrwx. 1 root root 14 Feb  7 18:20 /lib/cpp -> ../usr/bin/cpp

That looks correct, but because /lib is a symlink to
/usr/lib, it's in fact wrong (because it goes to
/usr/usr/bin/cpp).

Version-Release number of selected component (if applicable):

dracut-014-81.git20120202.fc17.noarch

How reproducible:

?

Steps to Reproduce:
1. do dracut convertfs
2. try to run rpcgen or just /lib/cpp
3.
  
Actual results:

Symlink to /lib/cpp is broken.

Expected results:

Not broken.
