change in disks behavior between 2.1.18 and 2.1.19

[Stephen Fromm]

I noticed a change in cfengine's behavior when checking the free space
on partitions.

Here's a basic config I'm testing with:

---BEGIN---

control:

    actionsequence = ( disks )

disks:

    /bin freespace=20% define=root_full
    /usr/bin freespace=80% define=usr_full
    /var/lib freespace=80% define=var_full

alerts:

    root_full::
        "/ on $(host) is approaching full"

    usr_full::
        "/usr on $(host) is approaching full"

    var_full::
        "/var on $(host) is approaching full"

---END---

When run with cfengine-2.1.18, I get the warnings (as expected) for /usr
and /var.  When run on cfengine-2.1.19, I get the following:

---BEGIN---

cfengine:limbo: There are 3 required file(system)s missing on host <global>
cfengine:limbo: even after all mounts have been attempted.
cfengine:limbo: This may be caused by a failure to mount a network filesystem 
(check exports)
cfengine:limbo: or because no valid server was specified in the program cf.test

---END---

Please let me know if additional debug output is needed.
