Are there any explicit host requirements?
The readme says it's a base install plus a handful of packages (bash debootstrap dpkg-dev rsync sudo zsh) - a little confusing that bash is on that list given it's (1) already in the base install and (2) the relevant script specifically uses zsh?
What is the combined file size of the packages to be downloaded?
How much total disk usage does the process require to build all 6* ISOs?
(*Is it 6 or 8? i.e. Are pool1 and pool2 actually released ISOs? I don't see them on the current download page?)
update: Sorry, I realised this thread is a year old.
At time of writing, there's a preview Live ISO for Excalibur here: https://dev1galaxy.org/viewtopic.php?pid=57204#p57204
