I ordered another slice to play with on 4 September. I attempted again to install LEMP which I did successfully. I think the LEMP server has been doing a good job and few days ago I also tried restoring a backup image to my first slice, swapped IP's between slices, all my sites are now running off my original first slice.
So the second slice is idling and I deleted it today. I have played with it and updated my LAMP howto, I couldn't find use of it now.
I guess if I have spare time after dinner I better spend more time on the black and write keyboard to ensure better sleep.
