Sadly, the Lion Recovery partition/Internet recovery option does nothing for us Lion Server users... Why Server on my MBP? ... I'll let you know when I have a valid answer beyond, "because I wanted to." Anyway, as I said, Lion will not re-install unless you wipe with DU. Since my TM backup is 3.5 weeks old (never again... I promise...) I put my MBP into target disk mode, and am copying all of the contents of MBP's Mac HD to a spare HD on my Mac Pro via FireWire. My plan is to wipe with DU, install Lion, restore my 3 week old backup, and replace certain folders that I know have changed since the backup with the contents of all that I'm pulling off now. I will then proceed to cover my thunderbolt port with Gorilla Glue, and hope that it never bothers me again.
For the majority of you, it sounds like this will do nothing, but for anyone running Lion Server, with an incredibly old backup to work with, this seems like our only option.
