Err, yeah, that's probably more precise.

OK, I've seen it, but:
which file does it touch?? That's a complete mystery to me
(the initramfs-tools git checkout here does not contain that path).

Hmm, the patch was introduced in early moments from 3.7 prior to
3.8-rc1. Thus one could say that the non-covered window is only
a part of the small 3.8-rc1 step which is used by devel people only.
OTOH to retain the very important development property
of properly working regression bisects over all versions
(of regressions *other* than this USB boot effect, that is),
even that smallish window ought to be fully covered.
If it thus is decided to be a sizeable versioning issue,
then it really should be downgraded to 3.7 very soon,
in order to prevent a support window coverage issue.
