I have gone from 2.0R->snap1->snap2->last snap by the following: 1. Take a backup of /etc 2. Put the bindist somewhere handy and execute extract.sh 3. Edit the resulting /etc to suit my machine, maybe picking pieces out of my backup copy 4. Either drop in a kernel compiled on one of my other machines, or reboot with generic kernel, extract kernel src and compile one 5. reboot and all done. I haven't been struck by lightening yet, so I must be doing somthing wrong! I appreciate that some upgrades will make radical change to disk layout and hence need a backup->clean install->restore process, but all of this year's snaps seem to have been compatible to this extent.
