Yes in the Atacama desert in a copper mine 4700m above sea level. One
other aspect seems to be the cooling. It's maybe ridiculous to think
about that for the tiny JB, but our company has installed here several
servers from DELL and the most of them got problems with their SCSI
hard disks as well. Since we installed an additional air condition in
the server cabinet we got rid of that problem finally.
But it is an interesting topic, right?
Lets see, next monday, when I do my last 10 days period in the mine,
I'll test the daily build which was recommended by Linus and further
more, I put my Jukebox in cotton wool to reduce the shock waves when I
am driving far from paved roads with my 4 x 4 Truck.
