While provisioning a system registered with RHN Satellite, it fails with error message `Error creating the new RAM disk` with file preservations

Issue

• Provisioning a machine registered with RHN Satellite fails if there are configurations of file preservation.

• File preservation example:

/etc/ssh/moduli
/etc/ssh/ssh_host_dsa_key
/etc/ssh/ssh_host_dsa_key.pub
/etc/ssh/ssh_host_rsa_key.pub
/etc/ssh/ssh_host_key.pub
/etc/ssh/ssh_host_rsa_key
/etc/ssh/ssh_host_key

• The problem seems to be at merge-rd.sh:

CMD: ['/usr/sbin/merge-rd.sh', '/boot/initrd.img', '/boot/initrd.img', '/tmp/ks-tree-shadow']
D: Sending back response(1, 'Error creating the new RAM disk', {'status': 1, 'stderr': '', 'stdout': 'Usage: /usr/sbin/merge-rd.sh SOURCERD DESTRD /path/to/merge/from\n'})

• There is no /boot/initrd.img but /boot/initrd.img_koan exists.
