Previously the chown command wasn't traversing symlinks, causing
the new ownership to not be set for some needed files.
This change also ensures the crush map tunables are set to the 'default'
profile after the upgrade.
Finally redirects the output of a pidof to /dev/null to avoid spurious
logging.
