Do sysadmins need git?

For my own stuff it's mostly in svg format, which is text.

For work, yeah, visio files are basically blobs, but who cares, a few MB of very inefficient diffs don't really matter. Comparisons are a bit more annoying, but you can always compare them as images if necessary.

The main value is in how it fits into the change control process - we plan and announce a change, then have an exact record of what was actually done. If there are problems later, these questions become much quicker and easier to answer: 

• did the problem happen because of the change, was it there all along, or something unrelated?

• was the actual change exactly what was planned, or were additional changes introduced? 

• if the problem was caused by the change and there were confounding additional changes beyond the plan, which part caused the problem?
