6. Some more

"We migrated key functions from Windows to Linux because we needed an
operating system that was stable and reliable -- one that would give us inhouse control.
So if we needed to patch, adjust, or adapt, we could.“
-- Official statement of the United Space Alliance, which manages the computer
systems for the International Space Station(ISS), regarding why they chose to switch
from Windows to Debian Linux on the ISS
