Debian Reproducible Live images Wiki page

Roland, et al,

Thank you for your important efforts creating and documenting
Debian Reproducible Live images!!

I have several questions, comments, and minor code improvements
for your excellent Debian Wiki page:
    https://wiki.debian.org/ReproducibleInstalls/LiveImages

1) Configuration
   What are the requirements for RAM and /dev/shm?
   My 8G RAM laptop defaults to 3.64G /dev/shm.
   This is fine for a standard image, but in order to build
   a gnome-core image, I needed to increase it to 6.5G.

2) Updated preparation
   Code improvements:
wget -qN http://snapshot.notset.fr/mr/timestamp/debian/latest
export SNAPSHOT_TIMESTAMP=$(grep result latest | cut -d\" -f4)
export SOURCE_DATE_EPOCH=$(date -d $(echo $SNAPSHOT_TIMESTAMP |
        sed -E 's/^(....)(..)(..T..)(..)(..Z)/\1-\2-\3:\4:\5/') +%s)

3) Hook scripts
   You could change all instances of:
    if [ ! -e FILE ];
    then
      exit 0
    fi
   to:
    [ -e FILE ] || exit 0

4) Everything, or at least apt-cacher-ng and /dev/shm,
   should be incorporated into the Debian Live Manual at some point.

Thank you again!
