Well the good news is I created a pretty fine draft of an Eden Dev environment. I should have reviewed the TKL Client threads; but as it turns out, what I put together is very close.
One problem: Install of Eclipse from conf scripts killed the patch process - no errors were thrown, but no ISO was produced and .cdroot and .rootfs weren't cleaned. When I tried to remove them by hand, I got a long list of permission problems. Troubleshooting package by package let me to Eclipse or its dependencies the patch fails in either of the following cases:
apt-get install eclipse
apt-get install eclipse-platform
apt-get install eclipse-pde
On the bright side, I wrote my first init-hook (is that the right term?) to install on first use.
But this ideal for Eden's use scenarios. Anyone know how to resolve this tklpatch issue?
