What this snippet does
mount -a validates every entry now, rather than discovering the mistake at the next boot.
Expected output
mount: /data: can't find UUID=3f2a1c9d.
Why practise typing this
Typing disk & filesystem code builds muscle memory for the symbols and indentation Linux uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
