Well, I botched mine for good

Started update this morning, download packages went well but it hang during install. killed process, started again and got a bit further on before hanging again.
After killing it second time could not massage it back to shape again, so decided to reboot which did not go well, it's not booting any more; bummer.

Lucky I had this old sbj1 with me, am using it now until I get home and can reflash the SFOS image to my Nexus...
I have of course nightly rsync copy of my home so nothing's lost really except time...
