messed up updatedb.conf

updatedb.conf does not work ootb. Some script seems to write a "exit 0 # Pluto" at the end of the file. When "exit 0 # Pluto" is remove updatedb works again,

/etc/updatedb.conf:

PRUNE_BIND_MOUNTS="yes"
# PRUNENAMES=".git .bzr .hg .svn"
PRUNEPATHS="/tmp /var/spool /media /home/.ecryptfs"
PRUNEFS="NFS nfs nfs4 rpc_pipefs afs binfmt_misc proc smbfs autofs iso9660 ncpfs coda devpts ftpfs devfs mfs shfs sysfs cifs lustre_lite tmpfs$
exit 0 # Pluto
