>The customer IT manager informed me (via email) that he plans to spin a Windows VM server in place of the Linux. Just so they can use my product. It will probably take many weeks but the end user (the department that uses my product) will push IT to get this done faster. Which means, that for now I can go and try to put out some other fires :)

Last time I had a customer like that, it took them 13 months to build the new server. The first 11 were for the approval process, two days to set up the machine, and the rest to get me sufficient permissions to actually be able to install the app and set up SQL properly. Then I did it in two days.
