The common things is something like:

├─/boot                          systemd-1   autofs rw,relatime,fd=41,pgrp=1,timeout=300,minproto=5,maxpr
│ └─/boot                        /dev/sda1   vfat   rw,relatime,fmask=0077,dmask=0077,codepage=437,iochar

but "autofs" is ignored.

My old plan is to add some de-duplication function to libmount... now
I have a real motivation :-)
