/etc/init.d/brltty checks md5sum when not necessary

Binary package hint: brltty

In Ubuntu 9.04, /etc/init.d/brltty will check the md5sum of /etc/brltty.conf prior to checking existence and without reason.
This is a wasted operation during boot.

recommend removing this line:
BRLTTY_CONF_MD5SUM=$(md5sum /etc/brltty.conf)

And changing this block of code:
-------------------------------------------------------------------------
# /etc/brltty.conf may need to be propagated from the initramfs. (This is a
# pretty awful hack.)
if [ -e /dev/.initramfs/brltty.conf ] && [ -e /etc/default/brltty ]; then
 if [ -e /etc/brltty.conf ] && [ "$BRLTTY_CONF_MD5SUM" = "$BRLTTY_CONF_PKG_MD5SUM" ]; then
  mv /etc/brltty.conf /etc/brltty.conf.orig
  mv /dev/.initramfs/brltty.conf /etc/brltty.conf
 fi
 sed -i -e 's/^RUN_BRLTTY=.*/RUN_BRLTTY=yes/' /etc/default/brltty
fi
-------------------------------------------------------------------------

to:
-------------------------------------------------------------------------
# /etc/brltty.conf may need to be propagated from the initramfs. (This is a
# pretty awful hack.)
if [ -e /dev/.initramfs/brltty.conf ] && [ -e /etc/default/brltty ]; then
 if [ -e /etc/brltty.conf ] && [ "$(md5sum /etc/brltty.conf)" = "$BRLTTY_CONF_PKG_MD5SUM" ]; then
  mv /etc/brltty.conf /etc/brltty.conf.orig
  mv /dev/.initramfs/brltty.conf /etc/brltty.conf
 fi
 sed -i -e 's/^RUN_BRLTTY=.*/RUN_BRLTTY=yes/' /etc/default/brltty
