[Bug 1615185] [NEW] ubuntu does not remove folders for mounted drives in /media on reboot

[Rocko]

Public bug reported:

Whenever I reboot, if there are drivers mounted with corresponding
folders in /media (whether internal or external, btfrs, ntfs, or ext4),
after the reboot the original folder is still present and the drives re-
mount in a new folder. (Note that I mount drives in /media instead of
/media/<username> so that all users can access them, in case this is
relevant.)

eg if there was a file mounted in /media/drive, after reboot there is an
empty folder /media/drive and a new one /media/drive1 with the drive
mounted in it. A subsequent reboot means there will be /media/drive,
/media/drive1, and /media/drive2, and so on until I manually remove the
old folders.

I'm guessing that the issue is that systemd is not unmounting the drives
properly on reboot since is a problem in Ubuntu 16.04 as well as
yakkety. It's unlikely to be a lack-of-time issue since sometimes on
reboot systemd will wait for 90 seconds or more for the cryptfs swap to
unmount before giving up.

Title:
  ubuntu does not remove folders for mounted drives in /media on reboot

Status in systemd package in Ubuntu:
  New

Bug description:
  Whenever I reboot, if there are drivers mounted with corresponding
  folders in /media (whether internal or external, btfrs, ntfs, or
  ext4), after the reboot the original folder is still present and the
  drives re-mount in a new folder. (Note that I mount drives in /media
  instead of /media/<username> so that all users can access them, in
  case this is relevant.)

  eg if there was a file mounted in /media/drive, after reboot there is
  an empty folder /media/drive and a new one /media/drive1 with the
  drive mounted in it. A subsequent reboot means there will be
  /media/drive, /media/drive1, and /media/drive2, and so on until I
