This is cool! A very slight simplification: sudo tune2fs -l $(df --output=source / | tail -1) | grep -i created

If you do it like this: # tune2fs -l `df --output=source / | tail -1` | grep -i created It'll also work on all Bourne compat shells, not only BASH.

Could be improved by just adding -l option to df, in order not to add delay for non local FS: sudo tune2fs -l $(df -lh / |(read; awk '{print $1; exit}')) | grep -i created

If your are cloning, ghosting or using Acronis to distribute your OS this command reflects the image create not how old that particular hardware installation is. I tested this on a system I just "built" from an Acronis backup and the date was before the server was even manufactured.
