 For now, the simplest thing is installable kernel images (I assume
that's ONU images) for r151014, which is what our test environment
is using now and what we'd wind up on with all of our production
fileservers[*]. I won't be able to start any testing with the images
until this afternoon at the earliest, so I don't think it's urgent to
build them right away.

 Thanks for all of this!

[*: our production fileservers are currently at r151010 but we're
    already looking at an r151014 upgrade. having this fix as part
    of r151014 would make that upgrade definite, and there's other
    things in 14 that we want, eg >16 group support over NFS.
