At least I have this script in my rpms:

# This script can safely be run as root, it will reexec itself as user

if [ "$#" -ne 2 ]; then
  echo "usage: $0 [hex errorcode] [filename]"
  exit 1
fi

# fallback to su if runuser not available
if [ -x /sbin/runuser ]; then
  RUNUSER=runuser
else
  RUNUSER=su
fi

# force cyrus user for security reasons
if [ ! $(whoami) = "cyrus" ]; then
  exec $RUNUSER - cyrus -c "cd $PWD < /dev/null ; sh $0 $*"
fi

HEXVAL=$1
INFILE=$2

# files get mode 0600
umask 166

DECVAL=$(echo "ibase=16; $HEXVAL" | bc)

dd if=$INFILE of=${INFILE}.fixed bs=1 count=$DECVAL 2> /dev/null
mv -vf ${INFILE}.fixed $INFILE
