Upgrading from util-linux 2.14.2 to 2.15 and switching libblkid.so from
e2fsprogs to util-linux causes machines to be unbootable.

Caused by the following two commits:

    Revert "e2fsprogs: Depends on util-linux for blkid"

    This reverts commit c3ff13022ef5564b2c6dbc28226532ec7ee39a34.

    I'm not sure what's going on, but putting the dependency order correct
    breaks.

    e2fsprogs 1.41.4 used to provide blkid.
    util-linux 2.15 now provides blkid.
    e2fsprogs 1.41.5 requires blkid from util-linux 2.15

    e2fsprogs 1.41.5 no longer provides blkid and needs it from util-linux.
    util-linux 2.15 cannot compile without e2fsprogs.

    Currently:
    update e2fsprogs from 1.41.4 -> 1.41.5, removing libblkid.so.
        mount (from util-linux) now fails as it cannot find libblkid.so.1.
    update util-linux to 2.15, now providing libblkid.so.
        mount is happy.
    e2fsprogs is built with its old libblkid.so and seems to still be happy.
    with util-linux's libblkid.so as they are ABI compatible (just moved
    packages, AFAIK).

    After this fun switch:
    e2fsprogs will need to be cast after util-linux, since future updates to
    libblkid.so will come from util-linux and are required by e2fsprogs.

    Possible resolution:
    Leave in current state (as above) and only fix the dependencies after
    this switch has been in a few stable releases.

May be caused only if using castfs as during PRE_INSTALL of
e2fsprogs/util-linux libblkid.so is removed, but then needed by castfs to 
mount
and do INSTALL, leaving no libblkid.so available for mount to use and making a
system unbootable.
