https://launchpad.net/bugs/383697
* Merge from Debian experimental, remaining changes:
  - Since udev is required in Ubuntu, the hwclock.sh init script is
    not called on startup and the hwclockfirst.sh init script is
    removed.
  - Use wildcards for symbols file, since they use versioned symbols
    properly.
  - Remove /etc/adjtime on upgrade if it was not used.
  - Install custom blkid.conf to use /dev/.blkid.tab since we don't
    expect device names to survive a reboot
  - No lsb_release call in mount.preinst since we'd need Pre-Depends
    (LP: #383697).
  - Do not install initramfs hook, since our initramfs already handles
    including blkid.
  - Mention mountall(8) in fstab(5) manpages, along with its special
    options.

* For the case where mount is called with a directory to mount, look
  that directory up in mountall's /lib/init/fstab if we couldn't find
  it mentioned anywhere else.  This means "mount /proc", "mount /sys",
  etc. work.
