as a creature of habit, i boot with the toram option. i wanted to see how that works amid the options, and this may actually count as one of the options listed. but right now i'm not using any of the built in persist methods, if i want to save a setup i'll just copy the rc files to a folder and create a script that copies all of them into place. so it's a little like cloud. although i like to save the extensions for reuse.
i haven't gotten around to putting them on a custom iso in either a tce folder or option folder (like dsl allows, and tc seems to) but i may in the future. doing it this way could seem like more trouble than it's worth, but it should work from distro to distro, and i don't have to weigh the official options. it feels more like i'm being lazy, but doing things your own way is one of the great things about linux.
