This is great, even works when you change path to an older mounted file system.

function fs_created { sudo su -c "tune2fs -l $1 | grep create" }

the first grep can be removed and placed into the awk command, df / | awk ' /dev/ {print $1}' | xargs tune2fs -l | grep create

I use it like an alias: alias fs_created="df / | awk ' /dev/ {print \$1}' | sudo su -c 'xargs tune2fs -l' | grep create"
