Sounds like a plan.
I tried refractasnapshot on Trios, and the iso wouldn't boot. It hung after "starting scripts/init-bottom" but sooner than it does with Refracta. Right now, I'm trying again after patching /usr/share/initramfs-tools/init (as described in another thread). If it works, I'll post a script and a patch file to make it easy. Then I'll somehow incorporate it into refractasnapshot. Then we can unpin and unhold util-linux.
