So I took a stab at implementing this. To figure out whether or not a
remount is required, I had to start parsing all options specified in
the right order, which turned out to be non-trivial given that many
options are boolean singletons (e.g. ro/rw) thus I quite trivially end
up remounting things way too many times then needed.

However coming to think about it again, I wonder if a simple "if
already mounted and the mounts are specified in /etc/fstab assume a
remount is required" should suffice all cases. I'll try again to
implement that.

Title:
  fstab does not honor /proc mount options

Status in “mountall” package in Ubuntu:
  Triaged

Bug description:
  Passing mount options (here: "hidepid=2") for /proc via /etc/fstab
  does not seem to work:

  $ grep /proc /etc/fstab /etc/mtab /proc/mounts 
  /etc/fstab:proc                   /proc proc  nodev,noexec,nosuid,hidepid=2 0  0
  /etc/mtab:proc                   /proc proc  rw,noexec,nosuid,nodev 0 0
  /proc/mounts:proc           /proc proc   rw,nosuid,nodev,noexec,relatime 0 0

  Also, /etc/mtab and /proc/mounts are out of sync - are there plans to
  link /etc/mtab against /proc/mounts? (Note: I'm not particularly in
  favor of bug 906293, propsing yet another file to the mix).

  The system is a fully patched Ubuntu 12.04.1 LTS (i686) in an Amazon
  EC2 virtual machine.

  Workaround: add the following line to /etc/rc.local:

     mount -o remount,hidepid=2 /proc
