terminal – Is there a commandline swap for “ls” that reveals “firmlinks”

With macOS Sierra APFS got here with a brand new idea of “firmlinks”, typically described as being “between hardlinks and symlinks”.

A number of folders are actually at System/Volumes/Knowledge however are firmlinked to places within the root of the filesystem. Three examples I do know of:

• /Library -> /System/Volumes/Knowledge/Library
• /Customers -> /System/Volumes/Knowledge/Customers
• /Functions -> /System/Volumes/Knowledge/Functions

Is there a manner when doing an ls of / from the Terminal to see which entries in that listing are literally firmlinks? There isn’t any point out of firmlinks within the ls man web page. The switches of I do know of for ls that offers probably the most detailed output is: ls -alO@ / however it does not appear to inform me:
