    Redirect fuel-logrotate's pgrep output to /dev/null

    On Ubuntu nodes, root's mail spool occasionally gets cluttered by
    mysterious numbers coming from fuel-logrotate. Some might think it's a
    message from aliens, but in fact Ubuntu symlinks /bin/sh (which is used in
    script's shebang) to fully POSIX-compliant dash. It doesn't understand
    '&>' syntax, is custom bash extension. It has been replaced with proper,
    portable redirection.
