I'll just throw out findmnt here.

It does what mount and df do, only with more options and filters. It is part of mount -- IIRC today's mount just runs findmnt --mtab under the hood -- and therefore available on all modern Linux systems. I guess the article's author would have been happy with

    findmnt -s -D -e
    findmnt --fstab --df --evaluate

Very cool. Thanks for sharing! I added `-x overlay` too, to get rid of all the docker overlay mounts.

and it almost works, does not get rid of efivars... needed to add `-x efivarfs` for that.
