We found this to be a race condition supposedly within aufs. The script
that mounts the overlay does the following:
# perform the aufs root mount
modprobe aufs
mount -t aufs -o br:${localroot}=rw:${netroot}=nfsro aufsroot ${rootmnt}
Doing this results in the described problem - df reports 0 bytes free on
${rootmnt}.
The fix is rather easy while a little annoying:
# perform the aufs root mount
modprobe aufs
# wait a second to avoid a race condition; see
https://bugs.launchpad.net/bugs/382842
sleep 1
mount -t aufs -o br:${localroot}=rw:${netroot}=nfsro aufsroot ${rootmnt}
This all happens within the initrd, by the way.
Perhaps this should be documented somewhere.
