I think GP's point is that the filesystems used by someone self-hosting gitlab may not be the same as what gitlab themselves are using.

File systems can be weird. Sometimes the OS can be weird and fsync type calls may not do what you expect. At least at one point MacOS fsync didn't behave the same way as Linux (i.e. Linux should ensure the write is truly done and not just in cache so long as the drive isn't lying). [0]

Gitlab has a community edition. Not handling data well would be bad for their public image.
